Note that all the above posts are about GENERAL maths.

With the change to Standard Maths, textbooks have changed. Eg New Century Maths has been re-done with new authors I believe. While I haven't used the new NCM, I'm a fan of the 7-10 textbooks by the same authors.

I'm using the cambridge textbook for standard maths (prelim) atm, and finding it to be extremely good. HEAPS of questions, and graded (level 1, level 2 and level 3). your teacher may be able to obtain worked solutions for it too, which is also immensely useful.
