How many past papers per day?Watch
Past papers allow you to come across how they ask the questions and the type of questions.
But I tend to do 3~4 a week.
An average paper has a duration of 3 hours. How do you manage 10 in a day?Are you able to spare some time for a quick revision after that?
But im guessing 10 papers is an exaggeration. But if you know the examinable content inside & out (and have already been going through all the papers) you’ll be surprised how rapidly some people can complete past papers.
