What's coming

Built for real retention, not cramming

Every part of TechPrep is designed around actually remembering what you study, not skimming past it once.

🧠
FSRS Spaced Repetition
Each topic is scheduled for review based on how well you actually remember it, so time goes to what you're genuinely shaky on.
📚
485 In-Depth Topics
Full technical guides, not flashcard snippets: core concepts, architecture, trade-offs, common mistakes, and production considerations.
🎯
Smart Practice Quizzes
Weighted question selection keeps resurfacing what you got wrong, so practice targets real gaps instead of repeating what you already know.
