Another vote for Bryan Peterson's book Understanding Exposure. (I did find his other books to be less useful, but I really like this one.)
Your profile doesn't indicate where you're based. If you're anywhere near New York City, I can highly recommend the photography school I've attended (for level 1 and 2) classes: PhotoUno

One of the things I learned from this course is that, at least for me, I retained information better when it was spread out over a series of hands-on lessons. Their introductory course is 6 weeks (2 hours per week), and 2 hours is about my limit before my brain reaches "buffer full" when it comes to photography. I liked the class format, which was a 2-hour lesson with some theory, an in-class exercise (often fun) and a short homework assignment.
There also are some photography instructors/schools who offer crash courses, and these can be good for getting you started, or for tackling a particular topic, but I think that it's hard to absorb much after the first couple of hours. If there is a good camera store (or community college) nearby, it may offer workshops or short courses.
If there are no live courses nearby, then online schools might be useful. Bryan Peterson has established a school (Perfect Picture School of Photography) and offers a range of mostly 4-week classes (for about $195), plus an 8-week course ($395) based on his book Understanding Exposure. I haven't taken the latter, but I have taken a number of the other classes and found them quite useful. I like the format, which consists of a lesson that can be accessed online (usually a PDF file but occasionally video lectures), a weekly assignment, a discussion forum for all students taking the class at the same time, and feedback from the instructor on assignments (and you can see your feedback and that for other students, too).
I haven't looked at it myself, but we gave my sister-in-law this DVD course from the Great Courses:
Fundamentals of Photography (Never pay full price for Great Courses. There's usually a good sale and if the course you want isn't on sale now, it will be soon.)
