I am third year PHD, I have a funding package which provides me with a full TAship. This year I am being offered two 0.5 TAship (one of which is NOT in my field). However I was also given the option to only take 0.5. I am trying to see if only taking 0.5 would screw me up in the long run? Also how taking only 0.5 would affect my OGS. Would I get to keep more? Right now, from what I understand, I will received two 5000$ payments (september and january) + normal salary (TAship+grants) then in May I will receive another 5000$ however my TAship will be reduce by 5000 for the summer semester.
