UPCAT

Hello Avaneesh,A lot will depend on the candidate who are placed above you. How they exercise their choice. However, to help you I am attaching a link that will predict college for you. https://www.shiksha.com/b-tech/resources/upsee-college-predictor.

Yes, you have good chances to GET in JSSATE, especially for lateral entry, it is quite easy to get in JSS. Last year, there were many seats that were vacant.

Sorry to say but your rank is too high so you won't get any government college through UPTU. Try in some good private engineering colleges.

Since from this year (2017) onwards, HBTI (HBTU to be more specific) has withdrawn from UPSEE Counselling procedure and will take students through JEE Mains counselling so IET will now be the first preference of UPSEE candidates.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.

You might have a chance if you have any reservation criteria else give it a try. You have very great chances to get into this institute, with this rank. Attend the counselling and choose your options appropriately. Try Shiksha college predictor for better analysis.

GN means general caste category and BC means backward caste category.

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