I totally would recommend 911 Driving School - Kent. I like the way they teach, they seem to be very focused and they kind of drill the important stuff into your head and I just really like the way they teach.
My classes were like 2 hours twice a week and I think it was exactly what I needed from a driving school. Before I started I thought that it was all going to be really easy but once I started going to class I realized that there were tons of stuff I didn't know. I recommend them highly.
