Well, a semester's hard work paid off.
I just finished the second of my A+ exams, the Operating Systems portion. I passed, by the skin of my teeth, but I still passed.
The best part of it is, I completed my certification within my 90 days' probationary period with my employer, a fact that's virtually guaranteed to factor in come raise time.
Now, if you'll excuse me, this new A+ certified tech needs to go take a NAP!
