What’s one thing students do today that classrooms still don’t adapt to?

For me, one weird observation:
Students rewind YouTube videos 10 times for one concept… but in class everyone moves at the same pace.

If you could redesign learning from scratch for JEE/NEET students:

1. AI tutor
2. Personalized study plan
3. Infinite practice
4. Better doubt solving
5. Something else?

Curious what people would actually choose and why.
