IGCSE separate sciences and double award resources

hi,
im thinking of either doing separate sciences or the double award. if anyone can link any resources (on amazon) please feel free
if i take double science, im going to take igcse human biology so also would like resource recommendations for that too

are these type books good for double science or is it only suitable for the single science awards?

Hi!

I did AQA double science and I found those CGP revision guides incredibly useful as they simplify concepts in a way that is easy to understand (+ they includes little tips and tricks to remember things in a funny way).

Whether or not you choose to do separate sciences or the double award is up to you but despite doing double science at GCSE, I now achieve higher grades in A-Level Chemistry than my friends that did the triple award. What I would say is consider whether or not you want a 9-9 or 3 G7s (if the workload is too much to handle).

hi
are those books good though if for my exam board they only sell IGCSE biology, chemistry and physics in separate books? they don't have the double science version. just worried that the books will have more content that i dont need for double science

would this double science book be good enough? and i can get the CGP books for revision as im self teaching so it's a bit confusing.

im not very good at getting the right books. do they look good? ik u did AQA but would like to see if you think these are worth getting as it is double science
yes, i want to take double because i want to do human biology too as i love the content and looked at past papers and know lots of answers already so i think it's an easy grade and i enjoy human biology and it's good for the uni course i want to do.
thanks for your advice
