I’m doing IB Chemistry and Biology and I’m honestly panicking a bit because exams are very close and I haven’t properly started revising yet.

I know I probably can’t revise everything in depth anymore, so I want to focus on the topics that are:

• most important,
• show up constantly in past papers,
• are high-yield for marks,
• or are basically guaranteed/common every year.

Especially for Chemistry, I also want advice for:

• the hardest/highest-weight topics,
• topics that are always tested in Paper 1/2,
• calculations/data analysis I absolutely need to know,
• and any “if you only revise a few things, revise THESE” advice.

For Biology too, which units/topics are the most important and repeatedly tested?

If anyone has:

• topic priority lists,
• revision order suggestions,
• common exam patterns,
• or last-minute survival advice,

I’d genuinely appreciate it a lot.

Thank you 😭
