About
Lincoln Sheets
I am a mathematics student at Purdue University in the final semester of my B.S., with plans to pursue an M.S. in Applied Statistics. I have four years of tutoring experience and have helped students go from failing to passing—and well beyond.
My approach is patient and direct: we find where the gaps are, rebuild the foundations, and practice until the material feels solid. Whether you are catching up in a tough course or aiming for a strong test score, I tailor each session to your goals.

FAQ
Common questions
- Can I cancel a session?
- Yes, but you must cancel at least 24 hours in advance. Otherwise you are charged the full session fee, as I cannot fill your slot on such short notice.
- What subjects do you tutor?
- I tutor algebra; Calculus I, II, and III; differential equations; linear algebra; AP math; and statistics. I also offer SAT and ACT math preparation.
- What is your availability?
- See the Availability section for my calendar, or reach out directly to find a time that works.
- How do online sessions work?
- We meet on Google Meet. After we confirm a time, I send you the meeting link. You share your materials—textbook problems, homework, practice tests—and we work through them together, step by step.
- Who do you typically work with?
- Mostly high school and college students, including those recovering from a rough start to a course or preparing for a major exam.
- What if I am failing the class?
- That is a common starting point. We identify what you are missing, work steadily through it, and build habits so you can keep improving between sessions.
- How do I book a session?
- Check my calendar for open times, or use the contact section to email or call. Tell me your subject, time zone, and when you are free.
- How do I join the session?
- Sessions use Google Meet. Once we have a time booked, you will receive a Meet link by email (or on the calendar invite if you booked through my scheduling calendar).
- Do you tutor students outside the U.S.?
- Yes. All sessions are online, so I work with students nationwide and internationally, as long as we can find a time that works for both of us.
