What is the best one for physics between these 3? and also, what is the best book for biology for most people in both subjects?
I hope i get a reply as soon as possible as im going to start studying AS first time for may/june!
Studying from only one book won't cover up all the syllabus. You can select one of the books, from those that I mentioned in the above post, which you find easy to comprehend as a core book and study it. When you are done with it then consult other books as reference and to cover up the areas that weren't touched in the book you were studying earlier.
For Biology:-) Biological Science by D.J. Taylor, N.P.O. Green and G.W. Stout
-) AS/A Level Biology by Mary Jones, Richard Fosbery, Dennis Taylor and Jennifer Gregory
