Cut offs change every year depending on various factors like Total no.of seats available, difficulty of the exam, previous year cut off trends, no.of Candidates appearing for the exam and no.of Candidates applying for a certain course. And ironically, Lockdown has nothing to do with cut offs. The no.of Candidates who appear for July session will be comparatively higher than those appearing for January session and so the competition is higher. Students will be preparing for the exam and you cannot do anything either about the competition being high or Students preparing for the exam. This is beyond you and you cannot overcome it. There is no advise or suggestion for that. What is well within your abilities and within your control is how you prepare for the exam. So what we can advise you is to work hard and do your best.
