Dumb conceptual question: Do the parallelogram and extension of exposures method result in the same outcome when bringing premium to the current rate level?

No. The parallelogram method is a rough approximation while the extension of exposures is precise. The extension of exposures method re-rates each historic exposure using the current rating algorithm and factors while the parallelogram method adjusts each by the average change for the group (year).

For the TIA:
In the solution for exercise 1 on c.4.8 - likelihood test.. why is l(3) used when we should have used l(50)?

Should the prob go on to say the log likelihood at 50 is -619

I'm finding 86-180 to be the toughest of the SOA..like much much harder than all the first bunch and last bunch. Anyone else agree/disagree??

Finally got to that 7 EL (6.98, but I'll take it). Feel like I've ironed out everything I was shakey on. Time to grind these next 5 days. Good luck in your last minute prep everybody!

How is the formula sheet displayed on the computer? Is it literally just an electronic version of the print-out? (Though I'm assuming we'll have a separate calculator for normal distribution.)

It is almost just an electronic version of the print out, except it is divided into 5 sections (a cover page that tells you to round when using the normal table as well as gives you the standard normal density, continuous distributions, discrete distributions, chi-square table, normal table). Unless they changed it from C, it's an image file that can't be searched.

No normal calculator, you have to look things up on the table.
