Checkpoint Gate: Readiness for Semester 2
Readiness is a conjunction of evidence
Use this gate after the module assessments and semester project. Budget 2–4 hours for evidence inspection and defense, included in the semester integration budget. Do not repeat every module exam merely to fill another checklist.
| Area | Required evidence | Source of scoring |
|---|---|---|
| Proofs and discrete structures | Every module gate, proof repair and delayed recheck | Module 1 assessment |
| Combinatorics and graphs | Every module gate, counting model and graph certificate | Module 2 assessment |
| Probability and statistics | PS1–PS12, reproducible experiments, uncertainty and inference appendix | Module 3 assessment |
| Linear algebra | Every module gate, exact/numerical evidence and changed-case check | Module 4 assessment |
| Problem solving | C01–C10, lab evidence and changed-model handoff | Module 5 assessment |
| Integer arithmetic | I1–I6, signed certificate and complete cycle audit | Integer assessment |
| Calculus | CAL1–CAL7, exact calculations and numerical approximation audit | Calculus assessment |
| Synthesis | E01–E12 plus graph investigation and defense | Exam, project, rubric |
Preserve the distinction between practice, self-assessment and independent review. Private first attempts and repair logs need not become public portfolio material. Link curated, reproducible evidence through the portfolio index.
Defense prompts
- Reproduce one result from a fresh directory and explain its assumptions.
- Defend one proof or witness without running code.
- Change the graph or sampling model and identify which formula must change.
- Explain a numerical failure, a confounder, and a claim the data cannot support.
- State the highest-risk remaining gap and the exact repair evidence needed.
Decision and repair
Use ready, repair required, or self-assessed ready; independent review pending. Every required category must meet the rubric. A percentage average cannot erase a weak domain. Repair only the failing category, then use a fresh variant and a delayed 7–14 day recheck for retention. Exploration of later topics is allowed while repairing; do not record the prerequisite gate as passed early. Record date, evidence paths, assistance, reviewer or self-assessment status, weakest gate and next retrieval date. There is no automatic calendar-based pass.
Cross-module connections
Complete the model, units and error check during the existing integration review. Its four subchecks must each reach level 2 under the existing probability, numerical-judgment and calculus categories; no extra semester hours or replacement of module gates is implied.
