I kept saying I was going to start revising Easter, but I never did, then I started procrastinating about not revising over Easter and wasted more time... and hadn't started revising until the last 2 days of the next half term holiday... which I spent revising for French Orals, then after that, had a weekend to do English Lit which was the early exam.
Then I wasted more time saying I was going to revise and never actually working so the only revision I really did was the week before the exam, where I did 3 hours a day, then I revised about 3 hours at the end of day of every exam and 4-5 hours in the weekend between the two exam weeks.
The History Paper 2 was where I was really cutting it thin, I just did an exam in the morning (forgot what it was now), and had literally a few hours to revise... so I only revised Women's Suffrage (didn't have time for propaganda/recruitment, liberal reforms etc), and with A LOT of luck, it came up lol!!
Rear guard action here, for anyone doing GCSEs, I really suggest starting around Easter time!! I was just lucky.
Grades I got are in my sig.
