Alas, this dang economy isn't helping folks in college. My two college-aged young adults are struggling to even decide what will make them marketable once they finish school. Back in the Dark Ages, we didn't have to worrry so much about that.
I have to say that I didn't follow the "suggestions" of one career inventory. My two highest scores were Army Officer and Navy Officer. I once taught on a military base and when I told my students about that, they said they could see me in those lines of work!
Yep, some profs seem to take pride in having a history of giving "low" grades. Of course, technically a "C" is average. My younger son has run into several in particular at his school, since it is in the top 20 of the schools in the country. He just dropped Spanish, even though he had a B in it, since he didn't trust his prof. Alas, she was teaching for the first time and didn't know what she was doing. He made a C in Latin and decided not to take another course in it. Man, was that professor demanding! And he was the only prof teaching it.
My suggestion is to work toward that degree. I just read, even with all the issues, it's still better to get a college degree......
Remember that people often change careers in their lives, so you aren't necessarily stuck with what you first get into.

Okay?
