How AP lessons run
Mapped to the course
Lessons follow the units in College Board's course and exam description, in the order the student's school teaches them, so tutoring supports class rather than racing ahead of it.
Free-response practice
Most lost points on AP exams are in the free-response section. Students write full answers, and the tutor marks them against the published scoring guidelines.
Timed mock before May
A full timed mock in March or April shows which units still need work while there is time to fix them.

Questions about AP tutoring
Which AP subjects do you tutor?
Calculus AB and BC, Precalculus, Statistics, Physics 1, Physics C: Mechanics, Microeconomics, Macroeconomics and Computer Science A. They are taught by tutors with a PhD, a master's degree or university teaching experience in the field.
When should AP tutoring start?
For a May exam, starting in the autumn lets lessons follow the school's pace. Starting in January or later still works, but the plan then focuses on free-response practice and the units the student finds hardest.
Can you help with AP Calculus BC if my school only teaches AB?
Yes. BC adds series, parametric, polar and vector topics to the AB content. A tutor can cover those topics one-to-one while the student follows AB at school.
Do you have AP practice questions?
Yes. The Testlyn practice bank has question sets and timed mocks for AP subjects, marked on submission. Students use it for homework; anyone can try it free.
How much does AP tutoring cost?
We quote after the free consultation, because the fee depends on the subject and the number of lessons. Talking to us costs nothing.
Free AP mock exams
Full mock exams in the exam's own format, timed. Multiple choice is marked on submission. Sign in free to have free-response answers marked by AI against the scoring guidelines. Tutors read the result before the first lesson.
