Urgent sincere advice regarding FCPS part 1 preparation please

I am an old graduate and need to give part 1 now.

What are my chances of clearing October attempt if i start preparing now, as I don't want to let go of this attempt and consequently January induction. (I was stuck because of something and the matter has just resolved now).

I have no idea of current exam pattern, study material etc but I've cleared fcps part 1 exam once in 2018. I am in touch with some selective basic academic studies because of my teaching job.

How should i approach the situation, what should be my study resources?

Any relevant insight is appreciated!

Thanks!
