Stressed and confused

I got the result yesterday and failed which i kind of knew that i would. I was prepared for it. The thing is it's been 2 month since last attempt and only 3 months left for the next one. and I've only been preparing for group 2. didn't even touch group 1 modules. I got lazy. not I've been thinking of giving both groups together in June, which would be really difficult. it'd be my 2 attempt. I am sure that i would clear group 2 in June but Idk about group 1. I was well prepared for jigl, claw too I can manage. it's cafm and sbill that'll take some time.

should I go for both the groups? can i get fine with lectures and revisions in 3 months? or should I just give 2nd group and the 1st one in dec'26?
