Hello Anika, Let me explain the concept of cutoff. JEE Mains is conducted for two reasons. To screen students who are allowed to appear for JEE Advanced and for entry into NIT's. This time about 10L students appeared for JEE Mains. Now everybody has been given rank but only about 2.3L students are declared to be above cutoff. But only less than 10% of these 2.3 L are likely to get admission. So what to say about those who have scored less than cut off? Its simply a seive to allow only reasonable number of students to progress to next round. But yes, those below cutoff are simply discarded.

Hi Bharat,
You should give priority to course in which you are interested. BCA and B.Tech are different stream hence you have to choose one course and then make a choice accordingly.
Regards.

Year back means you are not able to qualify a minimum set of desired exams in an year, hence you are not promoted to the next year. Minimum exams you need to qualify is around 60% that is if you have 10 exams in an year then you need to qualify at least 6 exams to be promoted to the next year
