Hi, I'm actually a student who would like to have some advice on where I should get my school books from. I go to an international school (Discovery College) and passed the deadline for buying school books (Science and Math) and would like to know where to get these books from as if I order them now, it will take longer to arrive.

Extended Mathematics for IGCSE 3rd edition

Edexcel IGSCE Biology Student Handbook

Complete Physics Cambridge for IGCSE

Complete Chemistry Cambridge for IGCSE

Please and thank you.
