Uttar Pradesh

Since from this year (2017) onwards, HBTI (HBTU to be more specific) has withdrawn from UPSEE Counselling procedure and will take students through JEE Mains counselling so IET will now be the first preference of UPSEE candidates.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