My admission test is tomorrow and I almost never prepared due to depression, other burdens such as isolation, and the fact that I hate memorizing my native language's words. Last time I took the admission test 3 years ago, my native language scoring was what significantly dropped my score. I've done greatly in its other parts, though.

Despite that, my local university has non-admission test conditions for some majors, and one of them is my beloved Math, and Statistics and Operations Research.
When I signed up to the university, I placed Math+CS as first priority, then Math+S&OR, and lastly Math by itself.
In just a few days I got a message of being accepted to Math+S&OR.

Picking the other major besides Math has been my dilemma. Computer Science requires an exceedingly high admission score.

I mean, I can feel fine or great about my way, but with all the talk about CS being a good path for a secure comfortable job with good money, I'm worried I'm taking a backwards path, as I majored Computer Science in high school. I also feel that because of the low or less high demand in S&OR, I'm missing something out.
One thing I can tell, I haven't been curious enough objectively about any of those majors.
Though from my set of mind I can tell CS is for constructing and maintaining machines in the form of codes, while S&OR are executive analyses of varying intelligence, for various goals. You can tell me if I'm wrong.

Any sort of help and information will be gladly accepted.
My family suggests taking the admission test since I may get a good score (though I highly doubt I'll get a good score for CS) perhaps if I'll want to change a major, but I also want to be determined and not have my mind loose on the "you can always change a path" mindset. It feels unhealthy to me.
I don't feel like taking the admission test since I see no point getting up early (so early I'll be really tired as I wake up at noon) to do it knowing I won't get a good score since I almost never prepared. My family says "you have nothing to lose", while I don't see a practical point to bother as my grade will probably not improve, and surely not enough for CS.
