I LOVE the SAT practice course. I often find myself digging up mistakes I've made and solving them to never see them again. That being said, when I run into a concept I've never learned, I struggle and find myself scouring the internet (and khan academy) to find the answer to my problem.
My most recent example of this is when I was working on the "Manipulating quadratic and exponential expressions" module and I ran into this problem:
Abhishek received an injection of a medication. The following expression shows the number of milligrams of medication left in his body after ttt hours.
Half-life of a medicine refers to the amount of time it takes for half of the medicine to leave the body. What is the half-life (in hours) of Abhishek's medicine?
After getting the problem wrong and reading how to solve it, I found myself confused and left still wondering why certain numbers were brought up in certain locations. Then, I looked at the videos and they apparently had nothing related to the problem I was attempting to solve (both easy and hard).
So I guess my suggestion would be to have more problem-type specific videos that can help someone like myself better learn the concepts behind some of the problems. Videos realyl are the best way I learn things so this really would help when it comes to preparing for the SAT.
Thanks for the great program and keep up the good work!
