Some People Like cambridge, some like fitzapetrik and some like maths in focus. i guess i was the only one who liked coroneos. I think Cambridge is better than fitzapetrik. but If you try Coroneos, then it is the best. but people do not like coroneos textbooks and i do not know why. when I read them, it is like a story and i enjoy from reading it.
also another good book is 50 3 unit tips and trick written by Mr.Gaha. I really suggest that if you dont like Coroneos.
Edit: lots of people like terry lee. I believe he is a great author because he tries to explain mathematics in an easy way but I honestly have never used it. The only book I was studying was Corones's one.
