B.Tech

Hello Mayank,
It is indeed heartening to know that in spite of doing your B.Tech in chemical engineering you are preparing to join an MBA programme. There are different specialisations in MBA which you can choose from but I would advise you to go through the list first and see which one of them fascinates you the most. This subject you should select since while studying you will enjoy the whole process as a subject fascinates you. There are literally hundreds of subjects in which MBA can be done but I am attaching link that will give you the best 5 out of them and you can go through it and then decide for yourself what you should do. https://www-shiksha-com.cdn.ampproject.org/v/s/www.shiksha.com/mba/articles/amp/top-5-mba-specializations-in-india-blogId-3223?amp_js_v=a2&_gsa=1&usqp=mq331AQECAFYAQ=#referrer=https://www.google.com&_tf=From %1$s&share=https://www.shiksha.com/mba/articles/top-5-mba-specializations-in-india-blogId-3223

Provided that students belonging to B.Sc category shall clear the subjects of Engineering Graphics/ Engineering.Drawing and Engineering Mechanics of the first year engineering program along with second-year subjects.
You have done B.Sc physics, which comes under science and not engineering, hence you might not be eligible for lateral entry in civil engineering, for more information contact the college authorities.

You can justify it by saying that scoring good percentage in graduation doesn't mean to have good practical knowledge. Percentage can be increased by studying theoretical books. There are many examples of people who didn't score high percentages/marks in their academics but they have better skills than toppers. Skills plays a vital role for success in industry. Ups and downs are the part of life. My low percentage shows downfall but cracking CAT exam shows up. For justifying no work experience, you can say how student can have work experience while studying full time. A fresher might have experience, but after working in any industry for some time, he/she can have experience.
