On Mahler 7, I did get that wrong, but only because I forgot to multiply by the (1+r)^5 which I factored out per TIA recommendation. It was easy chug and plug if you discount the expected value by (1+r)^5, then you don't need to worry about scaling factors at all. Mahler actually noted, "if you forgot to multiply back through by..." as he explained the alternate sol'n, my way HAHA

I had it set up correctly, but I went "NOPE. AIN'T GOT TIME FOR THIS." when I saw the E(X^d) formula. xD

Oh man. These Mahlers. 140 questions down, 375 more to go. I'm always behind my schedule, ugh. Was hoping to be halfway done by now.

yeah that's one that makes me cringe when I look at it. z and y are such simple ratios, so just organizing those values and being organized is crucial to get through it. I expect one or possibly two at most of those ugly distributions, but given they're so uncommon, the question may actually be not too bad with a little luck

Okay, checking in with
Mahler #8 - 15/20
Mahler #9 - 12/20

Is it just me or does Mahler #9 feature the oddest distribution of questions, with some too-simple-to-be-Mahler kernels/Bayesian/etc and some what-just-happened convolutions of what-is-that topics?

No idea where Mahlers/all these PE is going, to be honest ><" Such a huge variance in difficulty, topics, topic convolutions..etc

Mahler #5 Q13, is it at all likely the SOA would give such a hint

Highly unlikely.
I'm getting really burned out by Mahlers, haha. Frequently miss simple questions due to certain logic not clicking into place. Probably doesn't help that I sometimes do the exams after work, when I'm exhausted and whatnot.

yeah maybe try to review all passed exams before you sleep and wake up early. Do it before work when your fresh. It seems a little crazy at first, but after you get in the groove of it you will get used to it and be thankful you're more rested. It's an alternate time. going to bed early means you can get up earlier...

Seems like a theory but I've been working 3rd shift for over 8 years. It took me time to get used to but it's math . get your 8hrs sleep and that's all that matters not how early it is.

Did you do Mahler #10 yet? I started it and had to quit part way into it, so I could do it when I have more free time. the first couple questions seems very tough

I get up at 5AM to fit in some studying before work. I sometimes go to bed around 8PM, but I have trouble falling asleep until 10 or 11. Pretty exhausting, haha.

I just finished Mahler #10, actually. 11/20. Skipped Q1, skipped Q3, Q4 took me half an hour and skipped Q6. So, yeah...Mahler #10 is definitely one of the most exhausting Mahlers so far (Not sure if it's because it's Friday morning or if it's actually the worse of the bunch, though)

Took a bite of Mahler #11... the first full-length Mahler. Thankfully, it's finally Friday and I can sleep a lot more tomorrow, haha.

Here's an alternate idea for anyone taking Mahler shorter exams. If you want more time, then figure like this:

In theory, passing is 24/34, so if you choose to not answer 11, but simply guess which takes 5secs/question, then you have 11*6mins=66mins to redistribute those unanswered questions over the ones you choose to answer. Set a 2hr.+66min timer, so you have 8.75mins/question on the Mahler 20 Q PEs.

I have started throwing Mahler PEs between SOA 307 questions.

PE #1: 14/20 - Left 4 blank, guessed on 2
PE #2: 13/20 - Left 5 blank, guessed on 2
PE #3: 14/20 - Left 5 blank, guessed on 1

On the real exam and as I get closer, I will guess on everything that is blank. I also plan to go back and do the problems I left blank. I just wanted a clean gauge.
