For MHTCET, the eligibility criteria states that the student need to score atleast 45% in 10+2, in the Physics, Mathematics as compulsory subjects in addition with any of the subjects  Chemistry/ Biotechnology/ Biology. For SC/ST candidate, the passing marks for 10+2 is 40%.

So you are eligible for the MHTCET examination. The score required for the BTech varies from the college to college and the ranks corresponding to the score changes every year. So based on the college you are expecting to take admission in, you need to score the definite score. I would suggest you not to focus much on this, instead focus on scoring the best you can do.
