Willie saved me during a stressful time preparing for a graduate-level accounting exam. We had just learned some new concepts on equity (stocks specifically) that were throwing me for a loop, and he not only fit me into his busy schedule last-minute, but he was very patient in helping me apply the concepts I had learned to more advanced problems. In just one session, I felt much more confident in my knowledge of the material. Moreover, he was very polite and courteous throughout the whole lesson. His help was worth every penny!
