Hey, I was in the same plight as you just one year ago. I didn't consider engine courses because all that hearsay stereotypes of them. Go take a gap year, it's gonna be hard, the first few months with all your friends telling you how their uni experience was, not being able to hang out with them frequently etc, while you are stuck at work. I've been through it.
I was embarassed to see any ex-classmates or schoolmates because all the questions end up steering back to "Where did you go? What course?"(I mean if you're the kind of person who fears judgement from other people) Truthfully, those who mind don't matter, and those who matter don't mind so I just kept to my closest friends.
During that one year, I did research on the engine courses lah, I found that they are different from what the stereotypes. Perhaps if I just blindly chose engine last year, I might have been just the typical "just go for a degree" people. But I feel that I'll "treasure" it more now than ever that I've gotten to engine this year, also during this one year, I've improved on my people skill via work. So don't think of it as wasting a year per se. Think of this, what is that one year be compared to the future 60 years of your life.
All this is from my point of view.
If you're still on for business courses, Unisim is a great option. (Just don't go for Banking and Finance)
Good luck girl!
