SAT Math occupies two sections, the last two you’ll face on test day. The first 22-question section, or “module”, is the same for everyone. The second section, also 22 questions, is adaptive; see the detailed explanation in the introduction to the course. Put simply, those who do well on the first section get a harder second section and thereby have the best chance to do better overall. If that second Reading/Writing section feels hard to you, that’s good news!
SAT Math modules unfold with increasing difficulty as the section advances. This does NOT mean that question #12 is always harder than question #11 (especially since difficulty is different for different students, depending on their academic background and subject strengths); it does, however, mean that the early questions should feel simple, with only one or two steps, and the latest question should feel complicated, with many steps. This recognition gives birth to a strategy: if an early question feels easy, it probably is, so you can answer and move on. But if a late question feels easy, there is probably a trap; beware, and take an extra look!
The content areas for SAT Math are Algebra (linear equations and functions), Advanced Math (non-linear equations and functions), Geometry, and Problem-Solving and Data (including statistics). The first two categories account for 35% of the content each, while the last two categories each account for 15%. Note: this means that 70% of SAT Math is algebra! You cannot succeed on SAT Math without solid algebra skills.
These content areas are distributed randomly throughout the math section. This means that you may often have an algebra question followed by a geometry question followed by a statistics question. This distribution is not possible to predict precisely, so it’s another thing you can put in the “don’t worry about it” category!
Final notes: make sure to take the quizzes at the end of each lesson to make sure you have mastery of the content! And for the lesson-based questions that go from Difficulty 1 to Difficulty 5, you might skip Difficulty 1 questions if you generally find them too easy, or Level 5 questions if you find them generally too hard. Up to you! The course is at your service, to use as most suits your needs.
