DCFC, do you think CQF really worths the $$.
I have first to declare an interest, in that I teach
C++ on the CQF, and my business partner is Paul Wilmott.
If you are within the bounds of not knowing this stuff already, but knowing enough to understand it, then the expectation for most people is that it pays back.
A more difficult question is whether it is the
optimal investment in time and money.
There are other choices, most of which are more expensive, but it is still far from free.
Also it is a commitment in time which should not be ignored.
I think that's driven a lot by personal circumstances and ambitions.
When someone asks me, whether it is right for them, I generally have one of N replies:
0: A few are such clear cases that I tell them to do the CQF. That is only a tiny %. I always advise going to an open evening first, and typically set them up with an alumnus to talk about whether it is right for them.
1: Some simply don't have the background to get traction.
2: You're on the edge, take the maths paper, and/or do some more study in maths.
3: Some people have from/to that I can't properly model, so I put them in touch with an alumnus like them.
4: Some actually know enough that the marginal value is quite low.
5: Some want to do things that the CQF does not help with. For instance compliance, sales, or accountancy type work.
As a well known headhunter, I feel ethically obliged to give it to people straight, so I don't really "sell" at all.
