   Clear them

   Revisit each one until you can answer it, then mark it cleared.

• “Take a practice set from my mistakes.”
• “Which topics am I weakest in this month?”

• The Mistake Book itself costs no credits; generating practice from it uses the normal price for that tool.
• It only knows about questions you answered in Learnsable's practice, so it grows as you practise here.
• A mistake log helps only if you revisit it — schedule a short review each week.

• Mock Test GeneratorGenerate a practice test on any topic or exam: choose the number of questions and a timer, get answers with explanations, retake it, and track weak topics.
• AI Study PlannerBuild a weekly study schedule around your exam dates and tasks. Add constraints like “no study Friday evenings” and re-plan with one click.
• Student AI Voice MentorTalk to a study mentor that knows your plan. Start a guided session, get quizzed, have a topic explained or fix weak spots — by voice, hands-free.
