I agree with previous comment.
use common sense - officer who view your file should see some linking logical presentation of your case so that it doesnt' get tossed away for another rejection.
hope after reading this u will be clear
dont pay all fees at once which shows ur eagerness and potential immigrant reactions to VO
pay 1 semester fees
show remaining semester fees + living expenses in the form of loan or savings , fd etc (bank statement should make resonable details on how long money in held by you- dont pour all money overnight....
have seen 200 + cases so far - loan adds up possibility of visa
again, more you think - u confuse ur case, stick to what's been suggested and how people are doing ..
good luck
