<human>: Can you provide a brief rundown of the text in within 3 sentences?

So here's a little something about me. First off, got into a decent university and was accepted into their Aerospace Engineering Major. Started to do bad in physics, got Academic Probation because having mediocre grades (B-C) and an F (or 2, yeah Physics…) can really hurt. Dropped into Undeclared Engineering because of my belief that I wasn't all that bad (big mistake) and could still make it. 

Come summer, my grades were still relatively shit (GPA at 2.25, average for engineer student: 2.75). Took some time and asked my friends what they would do in my shoes (which was extremely hard, as they are all smart and I didn't want to be looked down upon…stupid pride), and finally decided, enough is enough. Switched out to Business Economics and now my Major GPA is relatively high but my overall is still a lovely 2.2 (Only my single variable calculus class was counted into my Major GPA)

My question is this, to all you people who look at resumes, if I were to send my Major GPA, would you then ask to see my overall GPA? Or is there not even an option to show your Major GPA and you automatically have to send in what your overall is? 

Also, I know that for the most part a lot of people have been telling me to not worry as much, because if I get an internship then for some strange reason, I'll magically be fine. But then my question is, a lot of internships ask for your GPA, what do you do in that case? (Submit overall or major?)
<bot>: I did bad in engineering, moved to Business Econ, will my old and bad grades from Engineering affect me for applying to a job?
