If you don't clear the remaining group this time, then you certainly cannot give final group 1 in November, can you?
You're sure you are well prepared with group 2 that you will clear it this time no matter how the question paper is set?
Answer these and I think you can answer your question yourself. Just a tip, in a hurdle race the runner has to see the nearest hurdle and jump over it instead of seeing the latter/ last ones or, he might just collide and fall.
Your friends don't know you or your capabilities more than you do. If you choose to take up tuitions and don't revise it after classes, as you might be studying Group 2 of PCC, what would be the point of it? You are most likely to forget what you were taught by the time you take up self-studies, then you may want to take up tuition once again.
You might immediately begin to prepare for Finals after giving PCC group 2 exams, you will still have 5 months to prepare 4 papers.. Even then some batches will begin.
