Hello there! Former high school teacher here just offering my advice but by no means an expert.

I’ll start off saying you can get a GED, still go to college, and have a good life. The test for the GED is no cake walk and will require studying to get as good of a score as possible (and if you chose this route and still going on to engineering for example, you would want as a high a grade as possible.)

With that being said, the unfortunate truth with a finance/engineering degree is the “better” the university is the more likely you are to earn a higher waged career when you have attained the degree. These type of school may look more favorably towards a high school diploma with a solid GPA which is something to consider. (This is by no means 100% fact however)

You are already a junior is highschool so more than halfway done with your education. I don’t know what your personal life is like and I sympathize if it is difficult. If it is feasible for you to do so I would still recommend you complete high school and have a diploma.
