I have been using TIA, but I was wondering if anyone would recommend Coaching Actuaries, Mahler or something else?

I think I mainly need to focus on doing more practice problems and it would be nice to have access to a forum for questions.

(6 C 4) (.75^4)(.25^2) + (6 C 5) (.75^5)(.25^1) + (6 C 6) (.75^6) why do we always expect 6? Couldn't there be 5 local and 2 express...6 local and 2 express...7 local and 2 express?
But in brief, to solve a probability question involving a set of events, you want to break the set up into mutually exclusive subevents, so that the probability of the set is the sum of the probabilities of the subsets.

By looking at all subsets of what the first 6 trains can be, you achieve this goal.

Your method does not lead to mutually exclusive subevents. For example, LLLLLEEL would be both 5 locals and 2 expresses and 6 locals and 2 expresses.

It sounds like you may already be aware of this, as a previous TIA user, but just in case, the MAS-I TIA course has around 1500 problems - most already have a video solution. Also, I answer questions in the TIA MAS-I forum usually within 24 hours.

Attempt #2 at this exam, missed it by 1 question which is unbelievably frustrating.

Thanks, Are more problems being released for the Fall 2018 sitting? In the work problems section I believe there were only 851 problems for Spring 2018.

All in. Took the last sitting of S. Excited to finally finish this thing and get my ACAS.

Yes, some will be added for the new lessons. Right now the counts are 850 for the problem system, another 400 or so in the sample exams and 250 or so more worked out in the lessons.

Didn’t pass C this past sitting. Debating between this or MAS-II. I am leaning towards this more though. How does one study for this exam? I heard TIA is good, I took a look at the source material as well. Are there practice exams that you can grind out with Coaching Actuaries like the prelim exams?

Starting my studying for this today...

One freaking question... makes me so mad. The only real pro is that if I can pass this and 6 in one go each, then destination = Hawaii for ACAS recognition.
