What are your favourite study apps? Watch
I know this is a level but we also used gcsepod in secondary school. This had podcasts on for all or the subjects - I mainly used if for history and was good to fall asleep to, listen on the way to school, or just take notes on.
You can put your timetable, exams and homework on it. I love the exam feature because I put the % of every test I do in my subjects and I can keep track of roughly how I'm doing.
And also, I never used the app, but memrise.com is a pretty good study tool. I make loads of Biology AS/A2 courses and it basically saved my History GCSE.
