Hello Aspirant,  There is good change to get the IET lucknow by this rank. Last year the cutoff rank for the IET lucknow for C.S.E branch is 2361 in round 1 and for round 2 it is 3362 and for round 3 it is 3362-5674. So there are lot of chances in 2nd round.

I hope this will help you.

Firstly congratulations for the marks you obtain. Last year I got 348 marks in upsee and rank 2616 in general category. I also want branch like CS and IT in IET lucknow but I don't get civil branch their. I don't know will you get CS branch in IET lucknow . And lastly how can you get 350 marks (350 is not divisible by 4 and I know that their is no negative marking in upsee). At last I hope u will get your desired college.

ALL THE BEST!!!!
