FAQ
CBSE Class 12 science: questions people ask
How do I balance three science subjects?
Give each a fixed weekly block and use a timetable. The study timetable maker can help.
Is NCERT enough for boards?
It is the core. Add sample papers and practice for the question styles.
How much time for practicals?
Start early, and do a little each week so the record file does not pile up.
Does it help for JEE and NEET?
Yes. The syllabi overlap a lot, though entrance exams need more practice. Check each official syllabus.
