I have taken several of my basic requirement classes at Bunker Hill. Some were great and I learned a lot... some were not that great. I think, though, that you just have to expect that you get what you pay for (and also that you get out as much as you put into it). A couple of my instructors were fabulous. One instructor was terrible. However, the classes were very inexpensive, with subject matter of moderate difficulty.
I believe that the school is pretty regularly ranked very high, as far as community colleges go, across the country. Also, this school was featured in "Good Will Hunting"! It is very conveniently located, with its own stop on the Orange Line (Community College Station).
If I were to do it all over again, I probably would find the four year school I wanted to attend, find out their basic requirements, start at Bunker Hill by taking those basic requirements, and then transfer into the four year school of my choice. It is a much less expensive option.
