@ninja_maths @CasserolePinoy @justinskycak @_MathAcademy_ Hi @ninja_maths any updates on the timeline for ACT?

@CasserolePinoy @justinskycak @_MathAcademy_ A full-on ACT prep course may take a while, but we could easily put together an "ACT Fundamentals" course similar to our SAT Math Fundamentals course. I'll give it some thought.

Everybody's out here talking about their upcoming winter math arc... @_MathAcademy_ itself is gonna have a winter arc too, churning out new courses like a firehouse! Prob/Stats next month, Discrete Math soon after, Machine Learning I in the spring. If you're still early in the Foundations sequence it's time to get a move on! 😉 Also keep in mind that, beyond the Foundations sequence: -- Math for Machine Learning will be a prereq for Machine Learning I -- Methods of Proof will be a prereq for Discrete Math

We’re proud to share that SchoolMint Recruitment has been recognized with three @TheStevieAwards, two bronze and one gold, in the 24th Annual American Business Awards®! Learn more in the announcement: hubs.la/Q04dr9fl0

At the Magnet Schools of America Conference last week, one idea came through clearly: magnet enrollment is no longer just about having a strong program. Schools also need strong recruitment. We unpack our conference takeaways and more in our latest blog: hubs.la/Q04ddK1J0

I don’t think people have fully absorbed just how big the declines in student enrollment are going to be. Eight states are projected to experience DOUBLE DIGIT declines by 2031.

Congratulations @ankurnagpal !! Thank you for letting me be a small part of your journey. I will miss your monthly investor updates 🎉

Congratulations @calcsam and @mastra - Excited to be part of your journey!

A CEO from one of our portfolio companies shared this with their team. I’m re-sharing it with their permission, because it resonated and reflects what all founders and CEOs should be communicating. -- We are living through a period of compounding change. And in moments like this, the biggest risk is no longer making the wrong decision. It is moving too slowly while the world moves around you. There are two paths. We can play defense: - Protect what we have - Optimize what works - Wait for clarity It feels safe. It isn’t. Or we can play offense: - Learn faster than the environment changes - Use new tools to solve old problems in better ways - And create entirely new strategies and businesses That’s where the opportunity is. Challenge yourself to do things faster and better than you have ever attempted. Stay uncomfortable. Stay on the front foot.

2/ AI hasn’t slowed the demand for software engineers (at least not yet) There are over 67,000 (!!!) eng openings at tech companies globally right now, with 26,000 just in the U.S. We don’t know if there would have been more open roles if not for AI or if AI is actually leading to more open roles, but since the start of this year, the increase in open eng roles is accelerating even more.

This CA “billionaire” tax is an unrealized gains tax. A unicorn startup founder becomes a paper billionaire around $5B val. At YC we avg 2 to 4 per year (!) This will kill startups and innovation in California since a founder is illiquid while instantly on the hook for $100M

@ninja_maths @justinskycak Awesome - please let us know when it's ready and if you are looking for early testers. Thank you

Yes, exactly. ACT will follow the same format: An ACT fundamentals course, followed and supported by a specific test-prep course. @justinskycak has already made some solid inroads in helping us to map out a ACT Fundamentals course, so we can probably put a "broad strokes" course together quite quickly. Mapping out and building the missing middle and test-prep courses is more time consuming, but once we have the broad strokes fundamentals course in place we can start thinking carefully about that.

Apologies for the radio silence from me over the past few months. I've been insanely busy with little time for updates. But since it's my birthday today (yay me) and we just hit a few major milestones, I thought today would be a good time for an update. Over the past four months, our two biggest challenges have been: 1. Updating the SAT Fundamentals course to include all possible "missing middle" topics. 2. Creating our SAT Math Prep course, our first-ever test-prep course. I'm delighted to say that we've now added all missing middle topics to the Fundamentals course, and the Math Prep course is now ready. We're testing the Math Prep course with a handful of students first and making sure everything is in order before launching to the general public. It will be generally available very soon! The Fundamentals course is designed to provide students with all the foundational knowledge and skills they need for success on the exam. It is what I’d call a “regular” Math Academy course, complete with fully granular lessons and lots of scaffolding topics, all designed to develop mastery. The test-prep course contains only the types of questions you’ll likely see on the SAT exam itself. There are no lessons or scaffolding KPs, as all explicit instruction and scaffolding take place in the Fundamentals course. The test-prep course focuses on developing automaticity with the types of questions that often appear on the exam, giving students plenty of repetition and doubling down on areas where they need more practice. The difference between the two courses is similar to that between doing regular training as a professional boxer (mastering the fundamentals) vs. preparing for a contest against a specific opponent (test prep). Mastering the Fundamentals: Before going anywhere near a boxing ring, you need to master the fundamentals. Footwork, strength, endurance, conditioning, defence, a decent jab, and a good working knowledge of all the other punches. If you don't have all these, then you shouldn't be stepping into the ring, and you'll likely get your ass handed to you if you do! Fight Preparation: This is about getting ready for the specific opponent you plan to face. Every athlete has strengths and weaknesses. Have you studied your opponent and trained specifically to counter their strengths and capitalize on their weaknesses? Without specific knowledge of your opponent and the appropriate training to deal with them specifically, it's likely that, despite your solid fundamentals, you'll still fall short. Training prior to a contest needs to be tailored to your specific opponent. Once students have completed the Fundamentals course (i.e., they have all the foundations in place and they are rock-solid), they’ll qualify for the test-prep course. The fact that they're allowed to transition to the prep course means they're ready to start training for a specific opponent: the SAT exam itself. We will NOT allow students to transition to the Prep course until they have mastered the content in the Fundamentals course! Training for the specific test you plan to take is crucial for success. Raw subject knowledge is not enough, but you cannot be successful without it. Acquire the raw, fundamental skills first. Then, once those are all in place, you’re ready to start preparing for your opponent. The SAT Math Prep course itself consists of 284 topics. However, well-prepared students “should” place out of most of it when they sit the diagnostic assessment. What’s more, we were able to identify a ton of hierarchical structure in the test-prep questions, which I wrote about this a bit here: x.com/ninja_maths/st…. Since then, the knowledge graph for this course has grown considerably. In short, this means students can gain implicit practice on less-advanced questions by practicing more advanced ones, which should allow them to progress through the course and master all SAT-style questions we have extremely efficiently. The Missing Middle The "missing middle" refers to the gap between the knowledge acquired through a standard curriculum and the specific knowledge and skills needed to excel on certain tests, such as the SAT. In regular curricula, these missing middle topics are usually either (a) not covered at all, (b) glossed over, or (c) treated as "problem-solving" exercises that the majority of kids don't get around to even attempting, let alone mastering. Over the past 3-4 months, we've added over 120 of these missing middle topics to the Fundamentals curriculum. The results of this effort have looked extremely promising so far. There are too many new missing middle topics to cover, but just to give you a flavor, here's a handful we've recently added. Algebra & Advanced Algebra * Parametrizing Systems With Infinitely Many Solutions. Helping students to parametrize lines not just in the form (t, f(t)), but also (g(t), t) and (f(t),g(t)), as well as recognize valid parametrizations (quite advanced for this level). * Equating Polynomial Coefficients - Students are often required to deduce information about two equivalent polynomials by equating their coefficients. Some kids will understand what to do right away (i.e., they can deduce what to do without explicit instruction). But for the majority of kids, explicit instruction is needed, and this is a *vital* skill that requires automaticity as it required quite often. * Time-Shifting Exponential Models - Involves rewriting exponential models using different time units (avoiding common pitfalls) and solving related problems. * Vieta's Formulas - A wonderful, easy-to-understand (and even prove) concept that makes solving problems about sums and products of roots of polynomials an absolute breeze. * Reasoning about quadratic coefficients using various theorems (multiple topics). Some of the more challenging problems involve deducing a relationship between quadratic coefficients. We dedicated several topics to this. The idea is to train students to know which theorems to apply to a given situation. Larger Systems of Equations - Helping students reason about the number of solutions to a system containing three equations (most standard curricula stop at two equations only). * Working With Equivalent Forms of Exponential Functions. I wrote about this here: x.com/ninja_maths/st…. I'm also preparing another scaffolding topic to provide more context. * Extrema of Exponential Functions - Placing domain restrictions on transformed exponential functions, and using that to establish possible maximum and minimum values. * Factoring Binomial Expressions Containing Hidden Factors - When given a polynomial equation to solve, students will "by default" want to multiply two binomials whenever they see them, but this is often not very efficient. Factoring is often more efficient, so you need to train students to recognize situations where it is more appropriate, including when some factors are partially hidden. * Determining Unknown Parameters in Systems of Linear Equations - Occurs quite frequently on the SAT. Easy if you've mastered it, quite difficult if you haven't (and they tend to make the SAT questions quite tricky). * Solving Systems of Linear Equations by Identifying Structure - I wrote a bit about this here: x.com/ninja_maths/st… Geometry & Trigonometry * Areas of Inscribed Triangles - I wrote a post about that here: x.com/ninja_maths/st… * Constructing Functions Representing Properties of 2D and 3D Shapes (Multiple Topics) - These sound like they should be easy. But questions on the SAT are designed in such a way to mislead students who misread the question, which is easily done when you're under time pressure. It's less about recalling the various formulas for area, volume, etc., and more about correctly interpreting the relationships between the dimensions of a given shape. * Surface Areas of Combined Prisms - These often involve setting up and solving systems of nonlinear equations. Also, before you get to the hard problems, it's important to check students understand that when you glue two faces of a prism together, you lose the surface area from *two* faces (not one, which is a common mistake). Students must also correctly construct expressions for combined surface areas, both with concrete examples and with algebraic expressions. * Recognizing 30-60-90 Triangles - Cool scaffolding topic designed to help students immediately spot when a triangle is 30-60-90, an important skill. * Reasoning About Congruent and Similar Triangles (Multiple topics) - Using their knowledge of the various criteria to determine when you have sufficient information to prove congruence/similarity. Problem-Solving and Data Analysis * Optimizing Sums, Differences, Products, and Quotients - Actually one of my favorite missing middle topics. Given X = {x_1, x_2,..., x_n} and Y = {y_1, y_2, ..., y_m}, how does one optimize x + y, x - y, xy, and x/y, where x and y are elements of X and Y, respectively? It's rarely taught explicitly, and while the sum and product cases may seem obvious, the difference and quotient cases are less so (these are the ones that usually crop up, too). Getting this right is a vital skill in some SAT problems—you don't want students trying to figure this out on the fly; it needs to be *automatic!* The actual topic uses notation/phrasing in a more level-appropriate way than what I've done here, but the core essence is the same. * Bounding Statistical Metrics For Grouped Data - helping students evaluate expressions like min(Mean(X) - Median(Y)) given data presented in various forms, very much supported by the optimization topic above. * Interpreting Descriptions of Physical Phenomena, and Interpreting Rates of Change of Physical Phenomena - I could write an entire post about just these topics. Essentially, training students to extract useful information from a detailed description of some physical phenomena (e.g., magnetic flux density), write down appropriate formulas, check the units balance, and use them to solve problems, usually in some kind of non-trivial geometric setting. There's a lot more to discuss, but that'll probably do for now. For anyone who wants to know more about the SAT courses and the missing middle, please keep your eyes peeled for more episodes of the @_MathAcademy_ podcast (I'm planning to make an appearance to discuss all this, and more, very soon 🙂).

@ninja_maths @ninja_maths this is super exciting. Would this be the same Math Prep Course used for ACT Prep (when the ACT prep test course is available)?

Here's a close-up of part of the KG for the Math Prep course. Lots of structure that we were able to exploit. Globally, it's quite flat. But since students should place out of most of it, most student activity should take place around the leaf nodes.
