Hello. It is hard to tell exactly now if it is a pass mark or not because NTA will declare the result after the April exam on the basis of overall merit list. The best of two percentile will be considered for people appearing in both jan and April. Your rank will be determined by your percentile and no. Of students appearing in April attempt. Meanwhile your rank for now can be calculated by the formula

Rank=(total number of students -(percentile*0.01*number of students))

Tot no. of students- 9.75 lakhs 

I would recommend you to prepare for April attempt and try to score higher percentile. A percentile of 85 and above can probably get you into a good college.
