HYBRID / OUTSIDE OF CLASS

Your independent work

Due Tuesday, March 9, 2027 at midnight, end of day.
The submission window ends Wednesday, March 10 at 12:00 AM America/Chicago. Wednesday class → following Tuesday deadline.

1. MeasureUP — every week

Complete at least one Core 2 · 220-1202 practice with at least 45 questions. Submit the question count, results and corrections or explanations for three weak concepts. Each course has its own weekly practice requirement.

2. NETLAB — graded assignments

Your weekly remote-lab portfolio is graded within the 20% lab category. The instructor assesses the work and evidence for each assigned lab; completion alone is not full credit.

Complete every approved remote-lab title assigned to this week. More than one lab may be required when several titles match the chapter material. Plan the assigned NETLAB work for the weekend after class. Reserve lab time early and allow time to troubleshoot, repeat steps and document results. Submit a remote-lab portfolio with a separate section and completion evidence for each assigned title.

Chapter/topic matching keywords: troubleshooting security recovery. Only instructor-approved title matches below are assigned. If none are listed, the catalog match is pending; do not assume that an unrelated lab satisfies the requirement.

3. Reinforcement and reflection

After the 108 class, revisit the chapter concepts used in Core 2 practical & readiness review. Complete at least one MeasureUP practice for this core with a minimum of 45 questions; submit question count, results and corrections for three weak concepts. Complete every instructor-approved NETLAB assignment listed for this module; one or several may be assigned when installed lab titles match the chapter topics (troubleshooting security recovery). Reserve access early, perform the lab individually, and submit a report for EACH assigned title with its exact name, completion evidence, interpreted results and troubleshooting notes. A lack of an approved link means catalog matching is pending, not that a specific vendor lab has been assigned. Submit the weekly reflection with one decision, supporting evidence and a professional handoff. All of this hybrid work is due at the end of the displayed Sunday for 107 or Tuesday for 108. Reading and handouts have the earlier before-class deadline; quizzes and classroom labs are completed in class only.

Time and dedication

Hybrid means that a substantial part of this college course is completed independently outside the classroom. An eight-week block compresses preparation and practice into a short term; it does not reduce the course's learning requirements. Budget 6–9 hours outside class per course each week, in addition to the three-hour meeting. Taking 107 and 108 concurrently means approximately 12–18 hours of independent work plus six scheduled classroom hours each week (18–24 total). These are planning estimates, not credit-hour guarantees; unfamiliar topics and troubleshooting may take longer. Read early, complete handouts before class, reserve NETLAB time in advance, allow time for failed attempts and repeat practice, and check deadlines separately for each course. This format requires sustained time, reliable technology access, weekly attendance and personal dedication; postponing work until the due date is unlikely to be successful.

IN CLASS ONLY / 5:45–8:45 PM

Prepare → Quiz → Chapter labs → Closeout

5:45–6:00 · Start-of-class quiz

Take the reading quiz at the beginning of class. Answer each prompt with a technical explanation; prompts are equally weighted.

Choose evidence-preservation steps; justify least privilege; specify recovery validation.

Use your preparation to explain the answer and the reason for it. Review missed concepts during closeout and add corrections to your study notes.

6:00–8:10 · Comprehensive lab stations

This module currently has 2 lab activities, approximately 60 minutes each, excluding the 7:00–7:10 break. The instructor may scope the tasks and demonstrations to fit the session. Weeks may use one extended lab, two standard labs, or three to four short chapter activities.

Lab 1

Practical: diagnose an OS or access issue, apply an approved fix and demonstrate functional and security verification.

Identify the support request, required outcome, authorized environment and safety or rollback precautions.
Record the starting configuration and symptoms. Predict the expected result before changing anything.
Perform the assigned procedure, capture relevant commands or settings, and troubleshoot unexpected results.
Verify the outcome with a repeatable test. Submit your observations, evidence, explanation and a concise service handoff.

Lab 2

Restore a disposable file set, complete a professional ticket and explain escalation boundaries in an oral handoff.

Identify the support request, required outcome, authorized environment and safety or rollback precautions.
Record the starting configuration and symptoms. Predict the expected result before changing anything.
Perform the assigned procedure, capture relevant commands or settings, and troubleshoot unexpected results.
Verify the outcome with a repeatable test. Submit your observations, evidence, explanation and a concise service handoff.

This is an original provisional sequence. Confirm chapter alignment and lab scope against the licensed text; the exact textbook lab sequence has not been extracted. In-class lab work and its evidence are completed in the supervised class period, not assigned as weekend hybrid work.

8:10–8:45 · Closeout lecture, Q&A and announcements

Core 2 domain review and a written remediation plan from MeasureUP evidence.

Connect lab results to certification concepts, resolve questions, review common errors, and confirm announcements, next week's reading and the hybrid deadline. Any make-up arrangements require instructor approval.

COURSE FINALE / TWO SEPARATE ASSESSMENTS

Comprehensive lab → Official certification exam

1. Comprehensive lab day — 30% of the course

The week 8 meeting is the comprehensive lab day: Wednesday, March 3, 2027, 5:45–8:45 PM. After the opening readiness quiz, complete one integrated practical with the assigned lab activities as its stations. All stations share the 30% equally. Work independently in the supervised, authorized lab environment; the instructor supplies the fault scenario and permitted tools.

Resolve an operating-system and security support incident: inspect system and account evidence, diagnose an assigned software or access problem, apply an authorized fix, demonstrate recovery or restore validation, and verify normal operation and least-privilege access.

Submit a single organized service portfolio across the assigned station submissions: intake and baseline, diagnosis and alternatives, procedure log, before/after evidence, validation tests, rollback or recovery plan, and a customer handoff. Rubric: correct procedure/result 40%; reasoning/evidence 30%; safety, permissions and data handling 20%; documentation 10%. Closeout includes a short explanation of your diagnosis, questions and exam-readiness announcements.

2. Actual certification exam — 30% of the course

After the lab day, take the official CompTIA A+ Core 2 · 220-1202 through an authorized testing provider. Schedule a separate appointment after the comprehensive lab and submit result evidence by Tuesday, March 9, 2027 at midnight, end of day, America/Chicago. Arrange voucher/payment, identification and testing requirements in advance; this portal does not deliver or book the official exam. MeasureUP is practice and does not replace it. The instructor must announce any approved deadline extension or retake arrangement.

Submit the exam code, date, official scaled score and pass/fail result through the private CertificationExam submission. Provide the official score report through the instructor-approved private method for verification; do not share exam questions or answers. The instructor verifies the result and records the scaled score in administration.

The published passing score for this exam is 700 on a 100–900 scale. For this course only, 100 maps to 0%, the passing score maps to 70%, and 900 maps to 100%, using linear interpolation below and above passing. This is the college course conversion, not CompTIA's percentage score. See the official certification exam information. Passing both required cores is necessary to earn A+ certification.

C-or-better course guarantee

If your pre-exam coursework average is at least 70% and you pass this course's official exam, your final course grade will be at least 70% (C). Pre-exam coursework includes the comprehensive lab and all other non-exam work, normalized over its combined 70% weight. Higher weighted results earn the corresponding higher grade. Missing or unverified exam results remain ungraded and count as zero until verified; they do not trigger the guarantee.
