Preston is an amazing tutor! He tutored both of my daughters in Finance and Accounting. My daughter said, “ Preston is great at explaining the processes to solutions, and how he came to the answers. He simplified to make things understandable. He offered extra help and study sessions.” My other daughter rated him a 10 out of 10! As a parent, he was an excellent communicator, and my daughters were both able to schedule sessions easily. They could arrange individual or small group sessions, based on their needs. We highly highly recommend Preston with 405 Tutoring!

Preston is an incredible tutor who goes above and beyond to ensure his students succeed. He is extremely patient, taking the time to break down complex concepts into manageable pieces so that anyone can grasp them. His teaching style is clear and structured, which makes learning not just easier but also enjoyable.

What truly sets Preston apart is his ability to build genuine relationships with his students. He doesn't just focus on academics; he cares about his students' overall growth and well-being. This personal connection fosters a supportive learning environment where students feel comfortable asking questions and expressing concerns. He consistently provides valuable study materials, practice exercises, and personalized tips to help his students excel. He is just awesome!!

I would not be able to get through my accounting and finance. classes without Preston. His tutoring sessions are thorough and very detailed so we all can understand every aspect of each type of question that the chapters have. I could not recommend him enough, he has helped me earn good grades in my accounting classes because they are fast paced and I usually need a little extra help. Most definitely use Preston, he is awesome!

I simply cannot recommend Preston Hartman and 405 Tutoring enough to any OU Business student or parent of an OU Business student! Preston’s tutoring program can help your student achieve their goals in accounting and finance! My son worked with Preston through both accounting courses and finance course and Preston’s program was a Godsend! He is an excellent communicator and has a way of connecting with young adults that allows them to trust him and believe in his methods, and they work! He helps them hold themselves accountable for their own learning, while lending a hand of guidance and support. As a parent, Preston kept me abreast of their progress and my son and I both developed a great relationship with him! He is simply an outstanding guy and cares deeply about how the kids do in their classes! Do not wait, get into his sessions, you will not regret it! He is the best. I am so glad my son had the extra support Preston offers in these courses.

Preston was extremely helpful and knowledgeable! With his tutoring I was able to not only pass the first two accounting classes (financial and managerial) but also receive an A! Could not recommend him more!

The best tutor at the university. Truly cares for all his students and knows how to fully teach each concept in a way a student would understand it, not just how a professor wants to teach it. I recommend Preston to anyone who asks!!
