Jan 26 Inter Guidance

Foundation (Jan 25) just got over, now I will be appearing for Inter in Jan 26. I have some doubts regarding Inter.

1) When should I order the books for Jan 26? Can I order it now?

2) I did foundation by self-study. Now for Inter, idk if I should go for online or offline classes. Many people are asking to go for purchased lectures and although I’m used to studying while staying at home, I’m also slightly concerned that I’ll mostly be home watching lectures for one whole year.

3) Which is better, giving both groups together or one at a time? I’ve heard G2 is harder than G1 too, so what are the comparatively harder subs?

4) During prep, should I complete one subject at once (cause that worked for me in FND) and then go to the next, or do 2-3 subjects simultaneously?
