Dear Student,

First of all , the range 134-720 is the cut-off range for a particular category. This means if a candidate has secured marks greater than or equal to 134, then he has cleared the cut-off , and now he is eligible to take admission in MBBS  colleges.

Now the second point is that how to get good marks in NEET.  So for this you have to be very practical. Work very hard, solve mock tests, solve previous year NEET papers. And also follow some good books for NEET. You can refer to the below link for that.
