Can I use prechewed as my sole revision source?

Prechewed Politics is a good revision source - however, it's essentially just videos and some news articles. If you find these revision techniques beneficial, then go for it! But I'd recommend a range of resources.

Thanks for your reply!
So you do politics? What tips do you suggest? There’s so much content and examples to learn!! How do you cope?

Sorry for not replying quicker! I did politics last year, and the best way to revise is to complete practice questions. Past papers are available on the exam board websites, and there's a load of practice papers here: https://www.studypolitics.co.uk/premium-resources/practice-questions/

As for the content, grab a revision guide from amazon, as they're great for revising the content and condensing it down. The best Edexcel one is https://www.amazon.co.uk/REVISE-Edexcel-Politics-Revision-Workbook/dp/1292221569/ or for AQA use the 'My Revision Notes' series.

Hope this helps, let me know if you need any more help
