@antonaut it’s really up to you overall though whenever you’re comfortable you can start. It’s perfectly fine to leave it til a little later as long as you’re doing your exam qs because if you think about it all those exam qs you’re doing esp when they’re timed would eventually add up to one paper? And like I said some sites do short papers but on specific topics so you get exposed to all types of questions but in one topic. Revise the content on the topics you really struggle with or haven’t covered at all. Anything else just straight up exam qs
@antonaut if you’re like 60% done with content you may aswell start answering papers. Aim to get like 60%-70+% of marks and that’s definitely a top grade. Remember not every single piece of content you learn is going to be in the papers and not every practical you learn or every equation you learn will be in there. If you’re still doing exam Qs by topic timed alongside your content revision that’s still really good. Certain websites do a whole paper but it’s just exam qs on a certain topic.
