i am in year 10 going into year 11 and i am using my gcse science to revise and learn some things i missed out or don't feel comfortable on (which is pretty much the whole syllabus atm). i was wondering if i should just use the website or use a mix of that and a text book or not at all. For my end of years i got a 5, 6 and 8. Sometimes it feels like the videos are missing things out. i really want to improve on my science and need to know if this is the way to do it.
