Paper 6 - IBS

I passed group 1 in Nov 2019, before Ind AS were part of FR. I wrote group 2 multiple times after the introduction of IBS paper. I am not able to get passing marks in this. I am writing again in Nov, 2026. Can anyone help me with these two things - 

1. How do I answer the FR part of the paper?
2. I study on my laptop through BOS - study materials. I do not have the physical copies of the books. Is anyone open to lending me books for 2 months or please let me know where I can get the books without having to spend a lot, it is only for the IBS exams.

Thanks,
