are there any like... proficiency tests I could take to find out what I'm good at?
I've heard something about questionaires about stuff you're good at, which in turn gives you majors that apply to those skills.
Anyone know where I could take one?
Great, so you're in the top 10% of people who took a test BELOW the SAT. That's like saying "I have the best 1987 Isuzu Pickup in town". Relativity blinds people.....you're still driving a piece of s***.
And english does not equal writing. The fact that you have decent reading comprehension and analysis skills has nothing to do with your writing ability. Truthfully, I've never met a decent writer who didn't work DAMN hard at it.
Not reaming you for it...just being straight.
As far as the PSAT, it is insignificant in the workplace, as are most tests. I don't want to lead you on in saying that most of this stuff is going to be significant in your future. While I know it feels good at the time, it really means nothing unless you keep developing skills and knowledge.
And believe me on this, I've taken more standardized tests and have more degrees than most anyone. Unless you have applicable skills, those test scores / ratings are pretty worthless (of which I learned the hard way).
Good luck.
