Difficulty of paper varies year to year so you cant go by score. And also dont use any cet rank predictor, they just predict your rank based on previous year’s score.
I’ll tell you the probable rank you need to get instead for CSE (Ranks mentioned below are an estimate for general merit category and for final round of counselling only and is just an indicator, need not hold true for the current year) -:
RVCE – < 200.
200–350 border line.
PESU – < 750.
750–900 border line.
BMSCE – < 800.
800–900 border line.
Hope this helps.
