Revision

Depends on your learning style, some like to see things so will benefit from YouTube videos, some like to do it and so will benefit from doing something over and over again and some prefer practical based which is what flashcards are for.

Also, what classes have you taken?

I have taken:
Triple Science-Edexcel
Business-Edexcel
History-AQA
Maths-AQA
R.E.-Edexcel
English Lit & Lan- AQA

Seneca may help, it's a free revision site with almost every subject and it'll cover everything you need to know and test you occasionally.
Here's a list of some revision sites I have saved on to my phone that you can check out:
Eng: dystopia junkie, click revision (insp calls), Mr bruff, Stacy read,
Mth: math genie.co.uk, Corbett maths, primrose kitten, fuseschool, Syd institute, wrightmaths, doctor jem, hegarty maths
Sci: freesciencelessons.co.uk, primrose kitten, science with hazel, Gorillaphysics,* doodlescience, fuseschool
Bpe: Haydon school REP Department (christ +Islam) MrMcMillianREvis

It really depends on your subjects.

English:
- Practise analysing but choosing random passages from books and articles, and annotating for litarary techniques, meaning and author's intentions.
- Practise essays on your given texts
- Learn quotes with quizlet
- Mindmaps for different themes as essay plans instead of having to write the whole essay.

Maths/ science:
- practice questions -> mark questions -> use textbooks, revision guides and the internet to improves topics that you can't do/ struggle with
- flashcards to learn necessary facts/ equations

Languages:
- QUizlet for vocab
- Practice talking to yourself and writing in the language - perhaps whrite a diary?
- Listen to music in the language

Of course, different methods will work for different people, so it's worth shopping around a bit. Just be aware that reading textbooks and not doing anyhitng with the informations is proven to be incredibly ineffective.

You need to find the way that works for you. For me it's half an hour hard studying, five minute break.

Thank you for your help.

No problem. Which subjects are you taking, btw?
