PRM Level 1

Is it necessary to go for any external training for PRM level 1? I have CFA and FRM training videos, Are they enough to get the understanding? I have not yet appeared for any of the exams like CFA, FRM or PRM.

If you have somehow experience about basic risk related subjects, you do not need I think

the key is solving a lot of questions mate

Can you share the videos/studay material please.
