Move from diagnosis through targeted review and timed sections, with the timing, calculator, and task-verb decisions that earn the points.
Eight weeks of AP Physics C: Mechanics, one week at a time
Each week names the AP Physics C: Mechanics units you work on and one thing you finish and keep. Tick a week off when the deliverable exists, not when the time is up.

One complete timed exam graded on the symbolic work, not just the final numbers.
AP Physics C: Mechanics exam strategy
A plan tells you what to study. This tells you how to spend the exam itself. Work these decisions into every timed week above, so exam day is a rehearsal rather than a first attempt.
AP Physics C: Mechanics timing: what one question is worth in minutes
Work out your pace before exam day so you never discover it during the exam.

Questions
Pacing note
Multiple choice
1 hour 25 minutes
42 questions
About 2 minutes each. Many are one derivative or one integral away from the answer - spot which.
Free response
1 hour 35 minutes
4 questions
About 24 minutes each. These are long derivation chains where later parts depend on earlier symbols.
Calculator and reference rules for AP Physics C: Mechanics
Calculator rules change from section to section, and they are different on every AP exam. Practice each section under its own rule.

What you may use
What that means for your work
Multiple choice
Four-function, scientific, or graphing calculator
Allowed throughout, though most items are symbolic or proportional.
Free response
Four-function, scientific, or graphing calculator
The hard parts are calculus, not arithmetic. Expect to integrate and differentiate by hand.
Provided for the whole exam
Equations and constants table
Both sections. Note that the table gives you relationships, not the calculus you must do with them.
AP Physics C: Mechanics task verbs and what earns the point
Free-response points are written for a specific verb. Answer a different verb and the work can be correct and still score zero.
Task verbs used on AP Physics C: Mechanics free-response questions
If the prompt says
The point is earned by
Derive an expression
Symbols only, from a named law. Set up the integral or the differential equation and solve it - do not quote a memorised result.
Show that
The result is printed. Every step between the starting principle and that result is a point.
Justify
Name the principle and state why it applies here, including whether the force is conservative or the system is isolated.
Sketch the graph
Label the axes, get the shape right at the limits, and mark asymptotes such as terminal velocity.
Rank
Order them and give the physical reason for the order, not just the list.
How students lose AP Physics C: Mechanics points
These are specific to this exam. Read them again the night before.
Applying constant-acceleration kinematics to a variable force such as drag or a spring. If the force depends on position or velocity, you need a differential equation.
Using I = MR squared for every object. Integrate for continuous bodies, and apply the parallel-axis theorem when the axis is not through the centre of mass.
Solving a separable differential equation and never applying the initial condition. An unresolved constant is an unfinished answer.
Losing the minus sign in F = -dU/dx. The force points toward lower potential energy, and the sign is the whole answer in stability questions.

Questions about AP Physics C: Mechanics eight-week study plan and exam strategy
How should I split eight weeks of AP Physics C: Mechanics revision?
Week 1 is “Diagnose and rebuild kinematics with calculus” and you finish it with one thing you keep: an error log plus ten problems where velocity and position come from integrating a given acceleration. Week 8 is “Full timed rehearsal”. Start at the week that matches the time you have left, not at week one.
How should I pace myself on the AP Physics C: Mechanics exam?
Multiple choice — About 2 minutes each. Many are one derivative or one integral away from the answer - spot which. Free response — About 24 minutes each. These are long derivation chains where later parts depend on earlier symbols.
What does “Derive an expression” mean on the AP Physics C: Mechanics exam?
Symbols only, from a named law. Set up the integral or the differential equation and solve it - do not quote a memorised result. Answering a different verb can be mathematically correct and still score zero.
What is the biggest scoring trap on the AP Physics C: Mechanics exam?
Using I = MR squared for every object. Integrate for continuous bodies, and apply the parallel-axis theorem when the axis is not through the centre of mass.
