Hello student, firstly I appreciate your level of perseverance as you really are a fighter to keep sticking to your goal and ulitamately being able to achieve it. To notify you that your past performance has really nothing to do with the standand of placement you will get. As most companies visiting your campus for oncampus placement would expect a good required skillset necessary to build their business, so they are least bothered how many attempts to took to pass 12th or how many drop years you had. For eg. if a software company like TCS visits, they expect your coding skills to be good, and also check soft skills like communication, attitude and confidence.

Now coming upon your CGPA, it is great if you score 9+ CG in your college years but it is rarely a criteria asked by any of the visiting companies on campus. In your interview you need to be honest with what you are and how much you know and be the rest assured.

All the very best with your future endeavours. Keep learning, Keep working hard!
