i would defo recommend the intensive course for cemap so you can book your exam on the back of that.
the actual exams are multi choice at your local driving centre.
the 1st is the hardest (financial law) especially if you have not studied for a while.
the remaining two can be taken during employment and are easier as they are based more on product knowledge and experience.
The trickiest thing is that they intentially try to mislead you in the question (use of double negatitives etc...)
I used an old Army term.. RTFQ...READ THE F*****G QUESTION
Once your brain is in gear, i found them relatively achievable to pass 1st time.
Good luck!
