Soon after I posted my earlier message on this thread, I had decided to quit my job and do MiF full-time, starting from next month. After a lot of research, the MS Finance at LBS is slightly less quanty than most FE programs but quant enough for me. I am in Fixed Income and want to be able to do structuring as well. While they have 2 semesters instead of 3 for quant stuffs, their other semester consists of compulsory subjects aimed at providing a firm foundation of finance from which you can develop all other branches. I think such design will give me a more thorough understanding of the world of finance and make me more confident at my job.
