Is there any Indian who has finished IPE (science)?

My indian friend will be taking her IPE exams next year (either in February or March). But she hasn't finished her syllabus because she had personal problems to deal with. Now she is totally depressed seeing how she doesn't know anything for her exams. On top of that, her college is making her take class tests to prepare for IPE exams. So she is spending all her time taking these class tests instead of knowing her syllabus. I have tried to help her as much as I could but I'm doing international A levels and I'm also not a science student. Plus, I'm not Indian.

So is there anyone who can tell me how I can guide my friend to finish her IPE syllabus in just 2-3 months?
