UPSEE

Since from this year (2017) onwards, HBTI (HBTU to be more specific) has withdrawn from UPSEE Counselling procedure and will take students through JEE Mains counselling so IET will now be the first preference of UPSEE candidates.
In 2016 surely you would have grabbed a seat in IET but not this year because now the cutoff rank will be much higher and close to the cut off rank of HBTI last year (2016).
It's quite difficult to get a core branch but you'll definitely grab a seat if you go for non-core branches in IET.
You can try for KNIT, Sultanpur or JSS, Noida if you priority is branch rather than college.

Actually, FIITJEE is better than Resonance for IIT-JEE Mains+Advanced coaching. FIITJEE is good in terms of practice papers, daily tests, doubts clarification, detail explanation, grand tests, etc.

Considering you're from general category, for mechanical you have slim chance though you may get some non-core branches.

Your chances would be high but you must check the official website of the college.

Hello Rakhi,
It's actually pretty bad to guess college where one can get admission. However to help you out, I am attaching a link that will predict college for you.

Yes, you will get the college. Rank is up to the stretch, keep an eye to the counselling. Good luck.
