Our mission & principles
We make test preparation accessible, effective and personalized for every student worldwide.

Learn through real exam tasks that mirror actual test conditions and difficulty levels.
Smart timing & pacing
Master exam timing with a built-in stopwatch and pacing indicators for every section.
Personalized strategy

Accessible for everyone
Quality education without borders — study from anywhere, at your own pace.
Built by students, for students
S&D Academy was founded by students who went through AP and SAT prep firsthand. After achieving top scores with our own materials, we taught AP courses for a year and refined our 80/20 practice-based methodology.
The goal is simple: give students worldwide the same resources and strategies that worked for us. Every MCQ includes explanations written by instructors who scored 5s themselves and tested the approach in real classrooms.
“Every student can achieve maximum results with the right preparation strategy and quality materials.”

Progress tracking and personalized recommendations
Every FRQ answer is checked by AI
Free-response questions are where most points are won or lost, and they are the hardest thing to practice alone. Our AI grader closes that gap: it reads your written explanation and your graphs, and scores them against an AP-style rubric in seconds.
- 01Write your answer
Explain your reasoning and draw graphs, just like on exam day.
- 02AI grades it
Scored point by point against an AP-style rubric in seconds.
- 03See every point
A per-part breakdown; unsure points go to human review.
Why practice-based learning works
- Active recall strengthens memory better than passive reading
- Real exam experience reduces test anxiety and builds confidence
- Immediate feedback — even on FRQs, thanks to AI grading — helps find and fix gaps quickly
- Time management develops naturally through timed practice
Smart timing & pacing
The built-in stopwatch tracks your pace so you finish on time on exam day.
