Hi!So,I am gonna start my preparations for these olympiads.First round is in Nov-Dec,so I've like 3-4 months max.This is the first time I'm participating in both of these olympiads(And sadly,it's also the last). Physics:I've An Introduction to Mechanics by Kleppner-Kolenkow,Problems in General Physics by I.E.Irodov,Resnick-Halliday-Krane,University Physics,H.C.Verma.Although I have all of these,I just KK and H.C.Verma.I just bought Irodov and I really like that book.What more do I need?For EM,I've heard Griffith is a good one.And what about QM? Maths:I just have M.L.Khanna,A.D.Dasgupta and a book that contains previous olympiads' questions.As you can see,I dont have too many books specifically written for the olympiads.I need tough high-school level books and esp. Geometry.I'm weak in Geometry.Well,not that weak,but I'm kinda scared of Geometry.I couldn't solve even ONE from IMO.I want one really tough geometry book and one other book which explains theory really well. Also,is Paul Zeitz's Art and Craft of Problem Solving a good book?I've heard a lot about it.But,is it worth 60$?Although,money isnt that big of a problem for me cuz I've got supportive parents.But is it as good as others say it is?Thank you!
