May 2025 Digital SAT: How To Prepare For The Harder Second Math Module

Does the second, harder Math Module on the Digital SAT feel impossible to you? Do you get to questions 15-22 on the second harder math module and feel completely stumped for how to even start the questions? Preparing for the second harder math section of the Digital SAT is a huge challenge for many students as most books, resources, and practice tests are not representative of what you'll see on test day. In this video, I am going to discuss what I have done to help many students get perfect or near perfect scores and prepare for the second, harder math module.

Details about the steps I recommend can be found at the bottom.

If you found the 1st math module relatively easy and the 2nd harder module much more difficult, I would recommend 3 things to get you ready for a much better score on your next SAT that have worked quite well for many students:

1. Get A Copy of The PrepPros Complete Guide to Digital SAT Math and sign up for the the Ultimate Digital SAT Math Course. ​
2. Work through all of the Level 3 and Level 4 Questions in The PrepPros Complete Guide To Digital SAT Math. These are the levels of questions that you need to master if you want to excel on the harder second module of Math.
If you only need to improve your SAT Math score, we would recommend purchasing our Ultimate Digital SAT Math Course. This course has over 50 hours of content and includes:

On-Demand video explanations to all 1,500 questions in the book
Tutorials on how to use Desmos to solve many of the hardest questions on the test
Lessons for all of the most advanced content that can appear on the Math modules
Advanced Digital SAT Math Course for Students Aiming for an 800. This course has 150 expert level questions that will prepare you to ace the hardest math question on the Digital SAT.
In depth explanations to all of the questions in the Math modules of the 6 bluebook practice tests
This full course is only $49.99/month when you enter a secret discount code from the front of your copy of the PrepPros Complete Guide To Digital SAT Math.

If you want to maximize your math score, you need to know how to solve questions in the most efficient way possible. Time management is crucial on the second harder module, so solving questions correctly but in a very round about way can have a significant impact on your score.

For the first exponential problem, just enter the given points into a table on desmos, then do the regression y1~ab^(x1/n). All the values for a, b, and n are solved for you. Then just type g(x)=ab^(x/n) and finally type g(9). Answer is 1215. Done. 20 seconds tops.

This is so true, there are so little resources for the content that are on the same level as the second harder math module.

[RohamAmina]

A life hack for the first one is to plug the two points into the table feature on desmos and then click on exponenetial regression then go to 9 and you will have your answer.

Watching your videos really helped elevate my score. I was able to prepare for the harder math module. I got a 770 on math. Thank you!

I think an easier/time efficient way to solve for #3 is by writing (x+3a)(3x + b) and let b be some number that we solve for. 3a * b will give us the c of a quadratic equation and since we know the c for all the choices is 18a, we can set 3ab equal to 18a and find that b = 6. Thus, the factored equation is (x+3a)(3x+6) and we can foil and find the answer. By plugging in numbers starting from 1, the only answer choice that will satisfy the terms for a is d

[Jay-yleq]

desmos for that last question makes it so easy, just type in each equation, and have a slider for a, and x+3a written out. Move the slider around, and if a is positive (not 0) while intercepting the graph at a x coordinate, than it is right. If it only intersects when a=0 or a negative number, then it is wrong. Really easy to do, and it will save a lot of time.

[Weatherr]

thank you so much, these were nearly the exact questions that confused me on the may sat

[quillerity]

for qn 4, what i did was, since x +3a is one factor then in the ans choices all of the x^2 term has a constant of 3. so, another factor shoukd be (3x + 6), '6" because all the choices has 18 as the coeffcient of 'a'. by doing that we get 9a+6 =24 (comparing correspinding vales of x), and boom a=2 (which is indeed a positive integer).

[Andrew-Tsegaye]

For question three you could solve this way easily:
(x + 3a) is a factor hmm... look @ the choices the coefficient and the y intercept are the same so we can generate another factor which is (3x + 6) perfect then expand it (x + 3a)(3x + 6) then set a = 2 [ because 'a' a positive integer ]

I'm really interested in this course but i'm already working a full time summer job to help out my family with bills and grocceries

[khasannishanov]

you can use regression on desmos to solve first one

[EyosiasYonas-nkth]

Can you show ways we can solve these through Desmos?

[adamsykes]

Lol I see myself in that email. Thanks for your help on the last SAT!

[notbrookem]

For the first problem why do the A’s cancel out and the B doesn’t?

[hoursaroundtheworld]

10:59 is C, 11:02 is x=2, 11:08 is 666 (not 100% sure about that one), and 11:14 is b=11.

[don-pollo-]

In the first question you don't need to do such a huge work just find the multiplication factor. So in the question g(4)=5 and g(7)=135 lets pretend this a geometric series and find the common ratio in this case 135/5 = 27 in a step of 3 points so cbrt(27) = 3 . This means that for every single step increased there is a multiplication of 3. To find g(9) just do 135*3*3 this gets us 1215 our ANSWER!!

[Sophia-lqjl]

Thank you for the video! Is there any way to use Desmos to solve this equation? I have SAT on June 1st.

[chaiboix]

ok skin we see you!! and thanks for da tips

He looks like if Chris Kratt and Ryan Reynolds had a baby
but this was very helpful tysm
