Intro
This checkpoint closes preseason with a mixed diagnostic. The goal is not a grade. The goal is to measure what is stable, what is fragile, and how the in-season plan should adjust.
Core Lesson
A useful diagnostic is broad enough to sample the real course and focused enough to reveal patterns. By now students have touched kinematics, force ideas, energy, momentum, rotation, oscillations, fluids, and exam structure. The diagnostic should mix those ideas the way the actual course does.
Students should treat this week as calibration, not judgment. A wrong answer is only valuable if it reveals the failure mode: wrong model, weak representation translation, careless reading, missing concept, or weak equation-sheet navigation.
The most important outcome is a better training plan. After the diagnostic, students should know which ideas are ready for faster pacing and which ones need deliberate revisit during the next phase.
AP Lift
Checkpoint weeks matter because AP growth is path-dependent. A clean mixed diagnostic lets students enter the in-season phase with realistic baselines and a study plan aligned to current AP Physics 1 demands.
Must-Master Objectives
- Use a mixed diagnostic to identify strengths and weaknesses honestly.
- Classify errors by cause rather than by question number alone.
- Connect diagnostic results to the next phase of study.
- Treat preseason work as foundation-building for later mixed retrieval.
Problem Set Prompts
- Why is a mixed diagnostic more useful than six isolated mini-quizzes?
- What is the difference between "I got it wrong" and "I know why I got it wrong"?
- How can a student tell whether an error came from model choice versus algebra?
- Why is it useful to review diagnostic mistakes by category?
- A student misses a fluids question because they thought pressure acts only downward. What does that reveal?
- How should a student respond if rotational questions still feel slower than linear ones?
- Why is a preseason diagnostic useful even if the score is lower than hoped?
- Stretch: Design a four-category error log for this diagnostic.
- Stretch: How should diagnostic results influence the first two weeks of in-season study?
Reflection Prompt
- Which topic now feels strongest heading into the next phase?
- What is the single most important adjustment you should make after this diagnostic?
