How to start prepare for CM1 &CB2

Hi everyone!

I’m an actuarial science student and I’m planning to start preparing for my first papers, CM1 and CB2, for the May/27. Since I have quite a lot of time, one of my seniors suggested that I try preparing for both papers together.

I’m a bit confused about whether I should go for two papers or focus on one paper at a time.

I Would really appreciate it if you guys could share your advice on this! Also, any tips on how to prepare for CM1 and CB2, especially regarding study materials, study plan, or how to approach the papers, would be really helpful.
