Expert instruction in AFOQT prep, SAT/ACT, Physics, Math, and Machine Learning — from someone who has actually used this knowledge in the field.
Every subject taught by someone who uses it professionally — not just someone who studied it.
Comprehensive preparation for all 12 AFOQT subtests. Strategy, timing, and content mastery from an active-duty officer who navigated this process firsthand.
Evidence-based strategies for Reading, Writing, and Math. Diagnostic-driven approach that targets your weakest areas first for maximum score gain.
From classical mechanics to nuclear physics. Conceptual clarity first, then mathematical precision. I bridge the gap between textbook and intuition.
Algebra through differential equations. I specialize in helping STEM students rebuild shaky foundations and advance rapidly through higher mathematics.
Practical ML for scientists and engineers. Python, neural networks, model training, and real-world deployment — taught by someone actively building AI systems.
ASVAB, OAR, ASTB, and other military entrance exams. Dr. Preston understands what the military values in these assessments and teaches to what matters.
No hidden fees. Direct booking means you pay less and I earn more. Everyone wins.
15-minute intro call. Tell me your goals, timeline, and current level. No obligation.
I assess exactly where you are and map the fastest path to your target score or skill level.
Every session targets your specific gaps. No generic curriculum — everything is built around you.
Track measurable progress every session. Most students hit their goal within the 4 or 8-session pack.
The intro call is 15 minutes, completely free, and zero pressure. I'll learn about your goals and tell you exactly how I can help. If we're a good fit, we schedule your first session.
No payment required to schedule. You'll receive a confirmation email immediately.
"The GOAT! Not many tutors genuinely care about giving you the correct information and are willing to challenge you and go the extra mile. Preston is very knowledgeable about the AFOQT material. If you don’t want to be challenged and receive the correct information, then don’t book him.👍"
"5 stars - Great First Session! We just had our first session with Preston, and it was a great experience! He is helping my daughter prepare for her AICE Marine Science exam retake, while also assisting with her current studies in Pre-Calc, and Chemistry. She was overwhelmed at the thought of tutoring, but he put her right at ease. Preston is knowledgeable, very supportive, and professional. Highly recommend!"
"Preston is a fantastic tutor! He is an expert in Machine Learning and artificial intelligence, having done first-authored research and possessing engineering expertise beyond the application layer. He is organized, disciplined, and a true master of the field. The best ML/AI tutor I ever met!"
