It’s fine to want a 9!!!
Aiming for a 9 in (I)GCSE sciences? You go for it!!!! It takes time and dedication- even for those apparently effortless 9s who claim they never revise (yeah - sure you don't)! But I’ve tried to make it as streamlined as possible with all in one topic and exam question PowerPoint guides with sufficient detail and practice opportunities that you don't have to search the web for a bunch of different resources to meet your needs. It’s fine to reach for a 9 - but an 8 is also great!
