How useless is doing past papers (especially for physics) that are REALLY old.
I noticed that my teachers assessments mirror the older style IB questions (since he doesn’t change his assessments for years), but I was wondering if using them (and omitting the content not covered anymore) is useful for exam prep. After all, the physics is the same, but how different really are the problems? It’s not to say I’ll be using new papers either, but for m27, learning the topics using those old papers could be useful. Thoughts?
