What students can expect

Serious progress without a stiff atmosphere.

Lessons are adapted to the student, the course, and the exact point where things stopped making sense.

No judgment

Ask the questions you think you should already know. That is often where real progress begins.

Clear explanations

Complicated ideas are broken into manageable steps, with the reasoning made visible.

Your actual course

Use your syllabus, textbook, assignments, exam requirements, and sample problems.

Useful technology

Digital whiteboards, Desmos, GeoGebra, spreadsheets, and programming tools are used when they genuinely help.

Subjects and curricula

From foundations to advanced secondary mathematics.

Mark primarily works with students from Grade 4 through Grade 12, with the heaviest concentration in secondary school.

Course matching

“Math 94” does not mean the same thing everywhere.

Course numbers and labels are usually local, not worldwide standards. To determine whether Mark is a suitable match, share the country, school system, grade level, current topics, textbook, syllabus, or a sample problem.

A useful first message includes:
  • Country and school system
  • Grade or year level
  • Current topics
  • A syllabus, textbook title, worksheet, or sample problem

Experience and approach

Experienced enough for parents. Approachable enough for students.

Mark’s lessons emphasize conceptual understanding, stronger foundations, exam preparation, and confidence. Lessons are conducted in English.
