as logn as the course hasn't changed in the past 2 years...I would say its the easiest actuarial exam you will sit...and probably the easiest exam you will ever sit! its good to look at the precourse material before the 2 days as i think they do check...but only look no need to learn at this stage... when it comes to the test (after the 2 day event) simply have everything printed infont of you and you will be fine.
Ct9 is like a thorn in the foot... Its always naws at you until you sit down and write it. The problem is you can write it anytime (so we get lazy) and you have no time limit. But once you sit down and write it it is by far the easiest exam you will write! Plus its open book! Wrote mine a month after i attended the course and passed first time.
