Hi anyone can help with cemap 2 and 3Watch
I would say you do definitely need to study for CEMAP 2 and 3. They do have a lot less content than CEMAP 1 and people say they are easier due to this but if you don't study for them then you will fail. There's no point booking the exam if your not confident as the exams are quite expensive and you'll be throwing money away.
I hope this helps and good luck in your studies!
