I kind of wish there was a driver's course in this group. One night a week where the weaker, less experienced drivers, could come together with a very experienced, patient, driver to walk us through the racecraft theory.
You should check out @

I know how you feel about not having the time to practice and improve. During the so get I have plenty if time. From now until the fall I will be able to practice sparadicaly at best.
