|
||||
|
||||
## Goal
|
||||
|
||||
Prepare to pass CompTIA A+ Core 2 by June 30, 2026.
|
||||
|
||||

|
||||

|
||||

|
||||

|
||||
- Question count: maximum 90
|
||||
- Time limit: 90 minutes
|
||||
- Passing score: 700 on a 900-point scale
|
||||
- Question styles: multiple choice, multiple response, drag-and-drop, performance-based questions
|
||||
|
||||

|
||||
|
||||
## Study Strategy
|
||||
|
||||
Use a fast exam-prep loop:
|
||||
1. Teach one small topic in plain language.
|
||||
2. Add a memory trick for the topic.
|
||||
3. Enter commands when commands are relevant.
|
||||
4. Explain what each command does and how to interpret the output.
|
||||
5. Run a Windows or Linux lab when useful.
|
||||
6. Quiz only after the section has been studied.
|
||||
7. Log mistakes by domain and objective.
|
||||
8. Re-test weak areas with spaced repetition.
|
||||
|
||||
Priority rule:
|
||||
- Security and Operating Systems receive the most study time because each is 28% of the exam.
|
||||
- Troubleshooting gets daily scenario practice because it overlaps with performance-based questions.
|
||||
- Operational Procedures gets frequent short reviews because it is vocabulary-heavy and process-driven.
|
||||
|
||||
## Progress State
|
||||
|
||||
Current status:
|
||||
- Study system created.
|
||||
- Objective 1.1 / OS-5 studied on 2026-06-11; quiz score 7/7. Status: Strong. Lab still pending.
|
||||
- Baseline quiz replaced by section quizzes after study.
|
||||
- OS-1 lesson/lab/quiz created: Windows editions and system information.
|
||||

|
||||
- All quiz answer keys were audited on 2026-06-10; correct answers are mixed across A, B, C, and D instead of always using A.
|
||||
|
||||
## Teaching Rules
|
||||
|
||||
Each section should stay small and easy to understand:
|
||||
- What it is
|
||||
- Why it matters on the exam
|
||||
- Memory trick
|
||||
- Commands to enter, if applicable
|
||||
- What each command does
|
||||
- Mini lab
|
||||
- Quiz after study
|
||||
|
||||
Quiz remediation rule:
|
||||
- If the user misses a quiz question, explain the correct answer.
|
||||
- Explain why the selected answer was wrong.
|
||||
- Explain what each answer choice does or means.
|
||||
- Update `quiz-log.md` and the HTML mind map status.
|
||||
|
||||
Quiz design rule:
|
||||
- Do not make every correct answer the same letter.
|
||||
- Mix correct answers across A, B, C, and D to prevent pattern guessing.
|
||||
- After creating or editing a quiz, verify the answer key distribution.
|
||||
|
||||
Mind map rule:
|
||||
- Use `mind-maps/core2-status.html` as the visual progress map.
|
||||
- Track status for each objective topic with levels:
|
||||
- Not started
|
||||
- Studying
|
||||
- Needs review
|
||||
- Good
|
||||
- Strong
|
||||
|
||||
## Memory Protocol
|
||||
|
||||
Before context limits or long sessions, update this file with:
|
||||
- Date and time
|
||||
- Topics completed
|
||||
- Quiz scores and missed concepts
|
||||
- Labs completed
|
||||
- Weak areas
|
||||
- Next recommended action
|
||||
|
||||
Use these files:
|
||||
- `SCHEDULE.md`: day-by-day plan through June 30
|
||||
- `quiz-log.md`: quiz attempts and mistake patterns
|
||||
- `lab-log.md`: hands-on exercises completed
|
||||
- `mind-maps/core2-overview.md`: overview map of the exam
|
||||
- `mind-maps/core2-status.html`: HTML objective status mind map
|
||||
- `reference-materials/`: user-provided Core 2 books/files/reference materials
|
||||
- `reference-materials/REFERENCE_INDEX.md`: index of processed references
|
||||
|
||||
## Reference Material Workflow
|
||||
|
||||
User may provide PDFs, EPUBs, images, text files, or unknown formats such as `.atm`.
|
||||
|
||||
When reference files are added:
|
||||
- Inspect filenames first.
|
||||
- Use `file` to identify unknown formats.
|
||||
- Extract or read text when possible.
|
||||
- Use references to improve original study materials.
|
||||
- Do not copy long copyrighted passages into notes.
|
||||
- Update lessons, labs, quizzes, and the HTML mind map from summarized concepts.
|
||||
- Track processed files in `reference-materials/REFERENCE_INDEX.md`.
|
||||
|
||||
Indexed references:
|
||||
- `/home/kenpatmonk/Downloads/Professor Messer’s A+ Core 2 Course Notes-1.pdf`
|
||||
- `/home/kenpatmonk/Downloads/Professor Messer’s CompTIA A+ Core 2 Practice Exams.pdf`
