Full-Length Timed Mock Exams, Remediation, and Exam Registration Verification

What This Lesson Is

This is the final practice session of the program. You will sit three full-length, timed mock exams under proctored conditions, receive scored results with a domain breakdown, complete targeted remediation if needed, and finish every administrative step required to walk into your live credentialing exams. Nothing here is optional — your course completion sign-off depends on meeting all three requirements.

The Three Mock Exams

NIMS Machining L1/L2 Written Mock. The mock follows the NIMS domain blueprint, which weights topic areas such as measurement and quality control, materials and tooling, machine operation, safety, and print reading. The mock contains 80 questions delivered in closed-note, timed conditions. Your instructor will score it immediately and return a breakdown by domain so you know exactly where any gap sits, not just your total score.

Mastercam Associate Mock Task Set. You will complete a full set of CAM tasks timed to match the published exam window. You will work from part files, set up toolpaths, verify toolpaths, and produce correct output — the same skills the live Certiport-proctored exam tests. Computers must have a licensed copy of Mastercam installed. No help files, no instructor prompts once the timer starts.

Haas Certification Mock. Working on the Haas Simulator or a live Haas machine, you will demonstrate every machine-control competency on the mock checklist: powering up, homing, setting work offsets and tool length offsets, editing a program, running in single-block and dry-run modes, and completing a safe shutdown. Your instructor checks each step against the competency checklist in real time.

Sit all three exams in a single proctored block. Treat the room like a live testing center: phones away, no notes, no talking.

Safety During the Mock Exams

The Haas mock takes place at a real or simulated machine. Follow all shop safety rules without exception, even though this is a practice session.

• Lockout/tagout (LOTO): If any tooling or workholding change is required between tasks, follow your facility's written LOTO procedure before reaching into the machine envelope. LOTO is not suspended because the session is a mock exam.
• PPE: Safety glasses with side shields are required the moment you enter the machine area. Closed-toe shoes and no loose clothing or jewelry are standing requirements.
• Machine guarding: Keep the door closed during any powered motion. Never reach into the work envelope while the spindle is capable of moving.
• Dry-run and single-block modes: Use these modes during verification steps before cutting. They exist to catch errors before a crash — use them exactly as you would on a production floor.

A safety violation during the mock is treated the same as it would be in industry: the run stops and the incident is logged.

Remediation Block

Immediately after scoring, any student below the current published passing threshold on any domain enters the structured four-hour remediation block. Remediation is targeted — you only work on the domains where you fell short.

• NIMS written gap: Instructor assigns specific practice items aligned to the weak domain. You review the material, complete the items, and take a short recheck quiz.
• Mastercam gap: You re-execute the specific CAM task type where errors occurred and submit corrected output.
• Haas control gap: You repeat the specific control procedure — for example, resetting a tool length offset or editing a parameter — until you can complete it correctly and explain each step aloud.

At the end of remediation, a recheck task confirms improvement. You must reach passing on the recheck to proceed to the live exam. Document everything in your personal remediation log — it becomes part of your exam-readiness portfolio.

Finalizing Your Exam Registration

Scoring above passing on the mock is only half of the completion requirement. You must also confirm every administrative step before your instructor signs off.

NIMS: Log into your NIMS online testing account, confirm your scheduled test date and site, and verify that your name on the account matches your government-issued ID exactly.

Mastercam Associate: Confirm registration through the Certiport portal or the authorized testing site your school uses. Verify the exam date, location or online proctoring setup, and any system requirements if testing remotely.

Haas Certification: Confirm enrollment through your school's Haas Technical Education Center (TEC) coordinator. The coordinator manages scheduling through Haas Automation's TEC network, so confirm the date and any site-specific requirements with them directly.

Exam-Readiness Portfolio. Assemble the following in a binder or a labeled digital folder:

1. Printed or saved mock exam score reports with domain breakdowns for all three credentials

2. Completed remediation log (if applicable)

3. Registration confirmations for all three live exams

4. A copy of your government-issued photo ID

Present the portfolio to your instructor for final sign-off. No portfolio, no sign-off — even if your mock scores are perfect.

The Day Before Your Live Exams

No new material to learn. Review your remediation log and weak-domain notes only. Confirm your exam time and location once more. Prepare your ID and any admission documents the testing center requires. Get a full night of sleep. Arrive early enough to complete check-in without rushing. You have put in 1,800 hours to reach this point — execute what you already know.
