Many tips can be followed only before class 11. However it still makes an interesting read due to the easy and conversational language. The section on Inorganic chemistry was HIGHLY useful. I plan on using all the tips as soon as I start with inorganic chemistry.
I got to know about this book from news paper review. I was bit pessimistic with the name .. Tips .. normally you do not get many practical take away points from such books. This one is different. Really great, pragmatic and do-able. This reminds me the best practices I used to follow while preparing for JEEs. But this includes many many more.
