The Forgetting Curve: How Often Should You Actually Revise?

Memory decays rapidly after learning. Within 24 hours, up to 50% of new information can vanish without active recall. Regular revision halts this decay, but timing is critical. Reviewing too soon wastes effort. Reviewing too late forces you to relearn from scratch.

Spaced repetition solves this problem. Each successful recall extends the safe interval between study sessions. Correct retrievals strengthen the memory, allowing longer gaps over time.

OptiEdu automates this entire process. The learning algorithm tracks your performance and calculates the optimal next review date for every topic. This removes all guesswork from your schedule.

The Review Tab, located next to the Lessons Tab, displays this data. Click "Focus on a Topic" to view a color-coded graph.

• Red indicates urgent review.

• Yellow signals fading knowledge.

• Green shows stable retention.

The same tab also manages your workflow. It lists all started but unfinished lessons for easy follow-up. Scrolling to the bottom reveals a progress breakdown for each topic, showing your exact completion percentage.

OptiEdu turns revision into an efficient, data-backed routine. Use the Review Tab to prioritize your next study session and focus on what matters most.
