Even though you may have a relatively low boards score, it is not a parameter to reject you as a candidate for the course, as far as it is above the minimum requirement for qualification.

Yes, you do stand a high chance of getting a call from Welingkar as they consider an overall score of your GDPI, your past academic records and also your percentile. Now, converting the call all depends on you.
