Yeah, I remember I saw that one and initially freaked out. but when you take the derivative of the integral, its just whats left inside @ t=10.5.

The only two that aren't looking good for me are the two toss-ups, 13 (cash flow) and 17 (UL). I guessed on 13 but initially felt pretty good on 17, but now I'm questioning whether I made a mistake there.
What was 13 again?

i did prob of being sick at the beg of year 3 (so two time periods) then 1000*prob and variance is 1000*(1-prob)*prob and then did the normal approx.
it wasn't four because i struggled with four.. and i remember totally guessing that.

Most calculators have memory functions with variables A-E, so toward the end if you have time some candidates might just code in a strings of letters (ie ABECDBE...) and just recall that without needing to remember what the question was since the SOA will release the exams later.

Didn't it ask for sick or healthy at time 3? Ugh maybe that's where I went wrong because my answer wasn't quite on there
