If u can arrange the class notes of Praveen sharma sir then it would be best option to u..
sir's class notes is very simple to understand the AS, simple language + example on every concept..
Praveen Sharma sir's book is d best for understanding the concepts.......but sometimes in the exam sums are taken straight from the book of D. S Rawat....so i suggest do from PS sir's book and just see the solved sums from rawat's book....solved sums will not take much time......
