hi,
see cutoff score changes every year and it depends on certain factors like number of participants, questions difficulty level, seat matrix, students category, choice of streams etc. however since this year written test would not conduct shortlisting of students would also depends on their 10th course marks in science subjects. however at this score you have fair chances in tier 1 colleges.
I suggest you to apply for multiple colleges as for making the best possibility of admission in your desired stream.
best of luck for your future endeavor.
