revision tips

Do testing frequently; break each topic into small chunks and then do switch between these topics as it ensures you remain engaged and take on all of the relevant info; use a variety of mediums when trying to understand the content - revision guides, lesson notes, online resources, youtube videos - by using more, you are more likely to both understand and remember it better.
And also be realistic in the targets you set yourself - don't try and revise crazy hours, but be disciplined in the time you do revise. For example, if you decide to do a 2 hour study spell, make sure you have no distractions (eg phones) in these 2 hours and try and be as efficient as possible! Good luck
