okay so clearly you are stressed like me, but after reading your concerns i have something to say, i think you are concentrating on wrong things, first of all your cgpa it's over whatever you do you can't change it now.instead you should fill your resume with projects and work experience. if you are worried that you took extra year to finish your btech, no one will ask so you don't even need to tell. there are all kinds of internships people do during college years, some do it for whole 7th or 8th sem for 6 months, some do it in summer, some do it in winter so chances are people will just assume you are in final year and unless asked you don't even need to tell so chill about your cgpa and year, but you really need to have something to talk about in your interviews so you need to be good at something or have portfolio of projects to show and discuss. i'm not in any position to help you, but we can talk maybe you'll feel better. it can be about anything your home, shit relatives, college ,friends. pm me if you want. quick question what two subjects do you need to retake?
