is 115-117 good marks for iift general category?

Not really, 140+ might fetch you a call.

sorry but no

45-50%b will be a safe score try to attempt about 75%, may be some smart guesses will also work. Best of Luck

score for 99+ percentile ???

can't say, it depends upon the level of difficulty. last year cut off was 138. Also, there are 5 ques wrong because of which +15 marks awarded to all.

no chance, last year it was 137
