By last chapters I mean Enviromental chemistry from XI and Chemistry in everyday life from XII.
I have 40 years but those are not covered there.
I suppose just read and remember everything. No book has questions from those chapters.
Everyday life mein itna example aur structures hai. How do they expect me to remember every detail?
Lol. Not saying remember all structures. Remembering the facts should be more than enough. And max to max ek question aata hai.
