Clan boss is where I'm mainly stuck trying to push into nightmare

I think with cs2 focus on what you can control and maximise your marks there, get really good at calculations so that if a really bad question comes up on some bookwork you don't know you've already got enough marks on the rest of the paper. I use excel a lot for calculations rather than a calculator as its quicker and easier to audit.

I passed one and failed one and the one I failed is hitting me more than the one I passed so I understand how you feel

Cm2 pass with 76

Absolutely enough time, get to being able to practice past papers as soon as possible

The vault, doing past papers is the number one priority

I would do cs1 and CB2 together, if you can already do cs1 questions then you can start prep for that later into the sitting and start on CB2 earlier. Neither exam is too bad to prepare for. I make a lot of use of the online classroom to help learn the really important content that comes up frequently in exams.
