I know how to do both 19 and 9 pm me and I can email you the answer. ---

Woops, meant 9; I got 19. I’ll let you know, thanks! When are you sitting? ---

Can anyone show the Franchise value duration how it is the negative inverse derivative of: FV = s\*(k-y) _cr / [(1+y)_(1+y-cr)]? ---

Okay so its negative inverse of Price \* derivative of price with respect to y. Or in Panning case it its negative inverse of Franchise Value \* multiplied by derivative of Franchise Value with respect to y. ---

Good luck to everyone! Window opens tomorrow. I take it the 23rd and just so ready for this to be over. ---

I’m taking it tomorrow so I’m off this thread after this. Good luck everyone! I hope testing centers stay open so everyone can finally take this! ---

Are we allowed to post tomorrow, if we are taking the exam much later. Asking questions on the material we are currently studying? ---

I think that if it’s clear your are asking about, say, how to solve question 13 from last year’s exam, or what the author means on page 45, yeah, you can post. I would strongly urge everyone who sits for the exam not to post replies to any of those questions, though. But I’ll defer to VA, who is really the exam mod. ---

In the same vein as act\_123’s question: I’m not sitting for 9 until December 9th but I’m sitting for 7 today. If you check the 7 thread, I made a couple posts with a lot of my notes and things I think that we should know/could come up on the exam. Would I be allowed to post something similar a couple days before I take 9 or is that not okay? ---

The problem is that the moderators don’t know who has taken which exam. Now that the exam windows are open, I don’t know if that’s a good idea. But let me bump that up to the mod forum for discussion. This is all new ground. Thanks for asking. ---

Sorry I’m a bit late in responding here more directly (one should use the @ feature to get one’s attention. 🤠) As Lucy points out, how do we know who has or hasn’t sat for an Exam? The moderators do ask for patience as they also figure out how this place works on top of how best to address everyone’s needs for preparation while still honor CAS/SOA requests around Exam security. Do know that we’re working on finding that balance, but it might take a sitting or two to get the balance right. ---

9 more days until I’m sitting now.. I worked through half of the 2018 exam this morning, so I’ll finish/grade it tomorrow then do the 2019 on this weekend. I’m feeling pretty good about my chances but at the same time I’m a bit burned out on studying and know there are some things that I definitely don’t know as well as I should. ---

So are we allowed to discuss past exam questions or sample exam questions (from TIA, CC, etc)? (I believe we can, but do the mods allow it?) I finished CC1 today and over all I don’t think it was too bad, but I didn’t take it under exam conditions. Had a few tricky questions, that I wasn’t totally sure about. In general, I don’t like CC too much, something about it just doesn’t jive for me, not sure what it is, maybe its her style/format, idk. I’m going to try to do CC2 and CC3 before my sitting and also focus on some of my weaker topics. ---

Is it required to memorize all the forms of riskiness leverage model, variance, semi-variance, etc.? 2020-12-02T06:00:00Z **`MOD COMMENT: Unfortunately, any response to this question should be vague and not delineate which ones "to memorize" and which ones to "not worry about".`** ---

I don’t think they’ve been asked on the 2011-2019 sittings, but I’m memorizing _ **.redacted.** _. I think just understanding the idea behind them should be good though, like semi-variance is similar to variance but _ **.redacted.** _, etc. Edit: Mods feel free to delete my comment if you think it’s inappropriate. I haven’t sat for the exam yet, so I’m just saying the things I’m memorizing on this topic. 2020-12-02T06:00:00Z _ **`MOD COMMENT: Thanks for understanding. I know that its a quirky sitting and doesn't help that there is a shitake-ton of changes in place.`** _ ---

> [@actuice](#): > > So are we allowed to discuss past exam questions or sample exam questions (from TIA, CC, etc)? (I believe we can, but do the mods allow it?) Unfortunately, not during active administration of the Exam. Too easy to “forecast” what is on the current Exam by referencing “similar” problems from past exam. ---

I made a few edits to some posts to remove content that might be construed as violating CAS’ request around Exam security. I’ve flagged those posts with “Staff Color” to facilitate any review; but note that no additional actions are being considered at this time. I appreciate everyone’s patience and understanding as we navigate this new space. Note that the moderators are working with CAS to get a clear picture of what’s “allowed” and we’re working to support candidates’ ability to discussion material in a timely fashion. ---

Take the position of having just finished sitting for the Exam and you wanted to know where \_\_\_\_\_\_ was covered in the syllabus . . . Would that be allowed to discuss during this time? As to your specific question, could someone who just sat for the exam signal others by asking such a question? How do any of the moderators know who has or hasn’t sat for a particular Exam? I do sympathize with y’all; especially those trying to tie up “loose ends”. And I appreciate y’all’s willingness to abide by our current expectations.
