Dr. Preston
Founder, FissionLab · AFOQT Community Leader

I finished my PhD in Nuclear Engineering at the Air Force Institute of Technology in 2025 — as the youngest graduate in the program. I'm an active-duty Air Force Captain with six years of service, and I've spent most of that time working at the intersection of physics, engineering, and operational problem-solving.

When over ten students who I'd helped prepare for the AFOQT asked me to create a community where they could study together and ask questions freely, the answer was obvious. This community exists because you all asked for it — and because everyone who wants to serve their country deserves access to real expertise without a price tag on it.

Dr. Preston holds a PhD in Nuclear Engineering from AFIT and has guided students to significant score improvements across every AFOQT subtest. His approach is built on deep subject mastery, not test-taking tricks.

Tutoring Philosophy

🎯
Diagnose First
Every student starts with a diagnostic. I don't waste your time reviewing what you already know — we attack your specific weak areas from day one.
⏱️
Speed Is a Skill
The AFOQT rewards trained speed as much as knowledge. We drill under real time pressure so test day feels routine, not panicked.
🧠
Understand, Don't Memorize
Memorizing answers won't work — the test varies. I teach the underlying concepts and reasoning so you can answer any variant of the question.
🤝
Honest Feedback
I tell you what the score means, what it will take to improve, and how realistic your timeline is. No empty encouragement — just actionable truth.
