  • girl this is the most helpful sat video ive seen. usually they give me the actual way to do it, even if it can be plugged into desmos, which is great for understanding the actual concept, but i honestly dont really care to do that. I just need the simplest and fastest way to do it so i can save the time for questions that actually need more thinking. And i lovee taking advantage of desmos. @Lig....

Dr. Test Prep in Action

Title I High School, Georgia


Dr. Michelle Ihrig created and implemented a free, voluntary SAT prep program (very similar to Dr. Test Prep) at a Title I high school during the 2020-2021 school year. Despite statewide declines in participation due to colleges dropping the SAT requirement, students in the Dr. Test Prep program chose to participate and test at higher rates than their county and state peers.
  • 300+ students participated in the program from 2020-2021
  • 200 students voluntarily took the SAT in 2020-2021
  • The school's participation rate declined only 14% from the 2019-2020 school year vs. decreases of 32% (county) and 31% (state) participation rates

Result: When access and encouragement meet, participation rises—even when testing is optional.
