Of course this was one of last few concepts I started understanding better in the last month so maybe my calculations could have been off.
A higher COI means a smaller AV which you got with the CF in play.

And, using common sense, has the SO ever asked a problem where they stated the CF and it ended up not being in play? I don't think so.

I guess what I need to pass exams is just plain old common sense... oh well. No, that certainly has merit.

Ah.. I just realized the dumb mistake I made at 17 and that made me loose more than 20 min. I found the "normal" ADB by 500 000 - AV6.

And then, applying the Corridor factor I found the AV6 but again did 500 000- AV6 to find the ADB, instead of multiplying by 1.5.

I got AV to be smaller without CF, I wonder where I went wrong in my algebra

I did the same thing. So far that is the only MC question I know for sure I missed. Trying to find the others....

use fact that curtate expectation of live aged 60 = 1 to solve for curtate expectation of live aged 61, plug curtate expectation of live aged 61 into expression of curtate expectation of live aged [58]+2, to actually solve for curtate expectation of live aged [58]+2, then add 0.5 to that to get the complete expectation of live aged [58]+2? Just curious.
I did it that way and according to the PAK it appears it wasn’t correct. This and one other where I was certain the right only to find I was overwhelmingly mistaken.

I cannot remember what letter choice I selected for that one.
