hi! i am doing my msc in biotech here in india. i wanna do my Phd in the states. i want to know about the subject GRE test and most importantly i wanna know about how i could get my full tuition fee off.. it'd be impossible for me to spend more than 7 or 8 lakhs from my own pocket and i know that for 3 years( most PhD programmes take 3 years) that amount is not enough unless i get a full tuition waiver. if i am not wrong on an average i have gotta spend 7 lakhs per year which includes everything. so 7*3=21 lakhs... that's too much. can you give me the actual picture of expenses in the US for a PhD student. I heard that i will be required to show my finances for the whole period of my course during the visa interview... how is that possible? I don't have anyone to guide me. please help.
