I am thinking that maybe the best thing you could for yourself is to see if they will do a private lesson. I know it normally costs more but then you have undivided attention and have someone who can really watch you while you actually do it - instead of you watching them. that normally works better for me.
The other thing that might work for you is to see if someone that was in your classes is really good at this - maybe you could get them to spend sometime with you, make a new friend and take her to lunch or make lunch at your house after you both work together for a while.
