Just to second what DeaconY said, I don't recommend getting into this game while a student. About 2 years ago I discovered FT while a grad student making about as much as yourself, got into the churning game and was terrified when suddenly one of the MSing opportunities fell through leaving me to hold on to about $2000 in gift cards that couldn't be liquidated easily. Long story short, I was able to liquidate about $1500 of it within a week but because of an issue with the reload card ended up floating about $500 for about 3 months until I contacted the BBB and finally had it returned.

Suffice to say, it was extremely stressful and at times I wasn't sure that I was ever going to get that $500 back. After that experience I dropped MSing completely while in school, and even now do it only very lightly to hit minimum spend.

On these forums it can often seem like everything is a piece of cake and nothing can go wrong, but just be aware that even after you've researched and started slow, things can, and do, go wrong. Don't gamble with anything you can't afford to lose.
