IMUCET

Yes, as a B.Sc graduate you can apply for IMU CET for postgraduate courses. For MBA or M.Sc in Commercial Shipping & Logistics, your Bachelor's degree with minimum 50% aggregate and 50% in English qualifies. However, for M.Tech programs, you need an engineering (BE/B.Tech) degree with at least 60% aggregate.

To join Merchant Navy, Physics, Chemistry and Mathematics (PCM) are required in 12th and most colleges require a minimum of 60% marks. If you have scored less in 12th, some options are still open:

Take Improvement Exam (next year) and improve your marks to get eligibility.

Some private maritime institutes also take those with 40–50% marks—but their placement is not that strong.

Alternative: You can do GP Rating Course (General Purpose Rating), for which eligibility is a little less (10th/12th pass with 40%+).

Once you get entry in Merchant Navy, you can grow later with experience.

No, candidates are not allowed to get admission into the BTech course without valid IMUCET scores. According to the official website of the college and other official sources, IMUCET scores are mandatory to get admission into undergraduate engineering courses at HIMT Chennai. Moreover, the college does not accept any other entrance examination score apart from IMU CET.
