• Entrance Exam Score (Approx. 40% weightage): A valid score in any of the accepted national-level exams (CAT,  XAT,  MAT,  CMAT, ATMA, GMAT, etc.) is a primary eligibility requirement for shortlisting.
• Group Discussion (GD) and Personal Interview (PI) (Approx. 60% weightage for the interview stage): Shortlisted candidates must participate in a GD and PI round. This stage is crucial for assessing a candidate's communication skills, attitude, problem-solving ability, leadership potential, general knowledge, career vision, and overall personality fit.
• Academic Performance: Consistent academic records from 10th, 12th, and the bachelor's degree level are also given significant consideration.
• Work Experience and Other Achievements: Candidates with relevant work experience, co-curricular/extracurricular achievements, social work, or additional educational qualifications receive extra weightage in the evaluation process.

Getting into the MBA programme of NIT Trichy with a 300 SC CAT rank is somewhat uncertain. As the recent data sets suggest, NIT Trichy's CAT cutoff for SC category admission stands around 65th percentile. A 300 SC rank could be borderline depending on how many SC candidates apply and the quality of the overall candidate pool.
In CAT marks terms, to reach around the 300 SC rank, you'd likely need a CAT percentile of 65–70, which roughly translates to a CAT score of about 60–65 out of 198, assuming the normalization and difficulty remain similar. 
However, final admission also depends on other factors like your academic profile, work experience, and performance in interview, not just CAT. So while you're in a reasonable range, make sure to strengthen your overall profile.
