Either way this thread is spiralling away from the original point which was "what's more relevant Physics or CS". What I'm getting from the discussion is that (aside from "smash" is not being an acceptable verb on this forum) neither have any relevance so I should just do what I enjoy the most at the present time.
I am not doing physics to get into finance as suggested, I just see physics as a subject with more opportunities and a way for me to get an insight into the inner workings of the universe and as pathway to a PhD project in theoretical physics. I am just as interested in computer science and potential further study.
You may ask, why am I on this forum then? The reason is that I stumbled into financial modelling and found it rather straightforward in all honesty. I found that I can read and understand research papers in finance and took an interest in time series analysis and stochastic processes and put this into practice with a load of Monte Carlo VaR models. I see finance as something that uses my existing skills in a practical and useful environment. I might then pursue a career out of that interest. I am currently interviewing for about 10-15 quant internships for the coming months before I start an MSc. as this might change the way I feel and could even lead me to choose an MFE program instead. I have had many interviewers ask, why I am doing an MSc. in Theoretical Physics, my answer above has satisfied all of them bar one so far.
I may be highly naiive but personally I see the MFE programs as something you could learn in your own time and as @
Barny said, it's all about the name on the degree certificate. From some extensive reading on these degrees, I think the £30,000 fees are largely to say "I graduated from
X university and did an internship with
Y company as part of my qualification."
It would seem to me that these courses are for someone who has already specialised in a mathematical subject, has some internships in a quantitative field under their belt and wants to take the plunge into quantitative finance. I see the MFE programmes (at least at the moment) as a highly specialised, risky and expensive gamble on getting into an industry that seems to be dominated by PhDs who already have experience in other types of modelling, have done quant internships as a taster and have decided to do an MFE to transfer their skills into finance.
I greatly appreciate the responses I am getting they are really informative and I do value the honesty in them.
