If you have started studying for p3 already, and you feel confident about p1 and p3, then go for them in June. If you don’t feel confident about both of them, I’d advice you write another paper and wait for SBL. It makes more financial sense because if you pass one and fail the other, you’ll still have to pay for SBL, which technically means paying 3 times for the same paper.
You should attempt it in June. 41 is close enough, and with a working technique, you would scale through. You already have some knowledge about paper p1 so you don’t have to study as though you are starting a new paper.
