1 month left

Got almost 40 days left, but I only properly started revising two days ago. After my mocks I felt soo burnt out probably due to how much time I spent revising for them and now I'm struggling to get back into it. Im starting to feel anxious since I really care about my academics and need a good set of grades for uni applications. Anyone got any advice on how to revise effectively? I especially struggle with English lan+lit (edexcel) and Psychology (aqa).
