Thoughts on the RACDS primary exam

I've applied for subscription to the Royal Australiasian college of dental surgeons. This is the first step towards taking the Primary examinations which is a test of Anatomy, Histology, Physiology, Cell Biology & Biochemistry, Pathology and Microbiology. It is a qualification that displays one's dedication to learning in the field of dentistry and is a prerequisite for many post graduate courses such as those in universities for specialisation and the grad dip conscious sedation that allows you to perform IV sedation in general practice.

I am still deciding whether or not to take the exams this year as they are quite full on. My thoughts are:
-This is a test of my dedication and willingness to learn. If I can't follow through with the primary exams then I am unlikely to be able to follow through in specialising.
-It is better to do this now as I haven't settled down to a long term job yet.
-It is better to do this early while I'm not too far away from my uni days and can still keep some form of concentration
-If I don't decide to specialise down the line at least I still have this to put on my CV. If I do decide to specialise I will already have this qualification ready to go. If I want to do the primaries down the line I will have to rush and it may delay my entry into a program.
