# CBSE Class 12 Board Exam Guide: Subject-Wise AI Practice Plan

CBSE Class 12 board prep benefits from subject-wise rotation: 20-mark Mingi worksheets on one weak chapter per weekday across Physics, Chemistry, Maths, Biology, and English, escalating to 50-mark mixed papers before school unit tests and 70–100 mark full mocks in the final month. High-yield chapters for most Science students include Electrostatics, Organic Chemistry mechanisms, Calculus (integration), Genetics, and English long-answer structure. Students retry flagged topics after 48 hours; parents review PIN-gated mastery trends weekly — not every answer in real time.

## Key facts

- Mingi generates 20, 50, 70, and 100 mark CBSE-style worksheets with AI grading and report cards for Class 12.
- CBSE Class 12 Science papers typically combine MCQs, case studies, numericals, and long answers with fixed mark weightage.
- Recommended daily drill: one 20-mark paper on a single weak chapter — sustainable alongside coaching homework.
- Learnability metrics from graded attempts flag topics below 60% mastery for the next drill slot.
- Mingi Starter plan is ₹499/month with 60 generations — often less than one coaching doubt-clearing session.
