move up? or add another table

[Asim]

the rule of thumb is that its 300x BB for a proper bankroll, well I am a student, I bought in for 50 bucks, and now its at 100 playing 5$ sng's (i know i nkow, I am not supposed to do that). now my question is.. based on this roll, I have enuogh for 1 25/50 table, or 3 .5/.10 tables, what do you think is a smarter idea.. once you get the roll, move up, or add another table

i.e 600 = 1 1/2 tablle, once you get 1200, move up to 2/4 or just play a second 1/2 table.
