Best books for A2 Mathematics (P3 & S1)?

I'm a bit behind on P3 and not taking tuitions. I need a good book, clearly based on CIE 9709 maths syllabus, which explains concepts in it well and concisely, preferably by touching on earlier concepts when relevant as well. Is there the maths equivalent to the excellent Physics and Chem ALevel coursebooks?

I'm good at picking up concepts just by reading about it but most of the books I've found seem to have too much extra content or are just not very clear.

So what are the most helpful books you know for guided A-LEVEL maths instruction?

This question is not from past papers it's from advanced level statistics by J.crawshaw and chambers.
Page no
Page 377 q6 and 9.
Q6)bags of flour packed by a particular machine have masses which are normally distributed with mean of 500g and standard deviation of 20g.2% of the bags are rejected for being underweight and one percent of the bags are rejected for being overweight?between what range of values should the mass of a bag of flour lie if it has to be accepted.


Q9)mean=400 and standard deviation is 8
A)find the limits within which the central 95% of the distribution lies.
B)find the inter quartile range of the distribution.



Plz solve these questions.thanks a lot!!
