Hi..Speaking clearly it all depends on the level of question paper.

But I would like to mention some recent trends here;

UPSEE 2018–452/600 yielded 1000 rank

UPSEE 2019–496/600 yielded 1000 rank

So as you can see there is a massive difference in the merit of these two so to get into HBTI core branches(cse,it,ee,ece,me,CE,chemical) you need to get around 1500 rank on a safe side.Speaking clearly it all depends on the level of question paper.

So marks wise try to score around 500+/600 that's try to correct 125+/150 questions. Practice well..

Hope it Helps…Good Luck..
