I am about to start class 12 in a few days and am currently gathering the best resources to study and practice from.

For mathematics i have bought KC Sinha for coordinate geometry and I am confused why is it that there are so many different books for each topic. Can you please reccomend me book(s) for the rest of the JEE syllabus for mathematics (apart from coordinate geometry).

Also is it necessary to buy 3 differnt books for organic,inorganic and physical chemistry? Or is there a good book which deals with them all exhaustively?

kept praying and believing he will return home, one day I told my friend at work what I was going through because I couldn’t bear the pain alone, that
was how she told me about DR mAHLANGU Traditional Home, i never believed her but something in me told me to give it a try, so i contacted him and he
told me the lady he is with now castled a spell on him, he said i should not worry, he said am going to receive a call from him in less than 24 hours,
on that faithful day i waited for his call till 12:00 NOON, my phone rang, guess who called, it was my husband Jonathan, he told me he did not know when or how he left me to italy, he said he was so sorry for every thing he made me go through, he told me he was coming back to me the following day, thats how i got my man back, if you want to contact this
