David, we as instructors never know what raw materials our students will have when they arrive. All we can do is assess each situation and use their raw talents to guide them in a direction that leads them to being successful. Each journey will be different but the process is typically the same in that we find a baseline and then continually move our students further towards an end goal. For some the difference between the base and end goal will be significant and require more of our time and effort. I have found these students to be the most rewarding in my career. James Jackson
