Yeah ,it is really confusing.So many Authors, so many styles. Some also give charts,summaries, ammendments highlighted. then live classes ,face to face, pen drive classes. Its crazy. Everything is expensive too. We have to find out what suits our learning temperament. That may take time. Self study may or may not work for someone. We may not like someone's voice or teachimg style and realize that later. We may not like book font or presentation style. Whether to take a comprehensive book or a summary or both is another concern. Vast subject . Preparation & Revision takes time.Not trying to confuse anyone. Many students buy several books but are unable to read them even once. Actual Examination paper may still be very tough.Anyways , some more good authors are :
Old classical :
1. T.N. Manoharan
2.Ahuja - Gupta
3.Shinghania
New :
1.Durgesh singh
2.Ravi Chaw....ria
3.Aashish Goyal
