26 Knowledge Gaps Tracker
26.1 Learning Objectives
By using this knowledge gaps tracker, you will be able to:
- Identify weak areas: Recognize topics where your understanding needs reinforcement
- Access targeted refreshers: Find focused content to address specific knowledge gaps
- Create a study plan: Organize follow-up activities to close gaps systematically
- Track improvement: Monitor your progress as you revisit challenging topics
In one sentence: Knowledge gaps are discoveries, not failures - identifying what you do not know is the first step toward mastery.
Remember this rule: When you score below 70% on any quiz, treat it as a learning opportunity - follow the structured path of read, watch, practice, and retest until you reach 80%.
26.2 Prerequisites
Before Using This Hub: - Complete at least one chapter from each major section you want to assess - Have access to quiz results or self-assessment notes - Set aside 30-60 minutes for thorough gap analysis
How This Hub Helps: This self-assessment tool helps you identify topics that need review. Unlike quizzes that test specific knowledge, this hub helps you discover what you don’t know.
Recommended Approach:
| Learning Stage | How to Use |
|---|---|
| Just Starting | Review “Spotlight Refreshers” to identify unfamiliar terms |
| Mid-Course | Use gap tables to find weak areas before exams |
| Project Work | Reference specific protocol/architecture gaps for your domain |
| Exam Prep | Systematically work through all gap areas |

26.3 Close Your Knowledge Gaps
Use this tracker when a quiz or lab reveals a topic you want to revisit. Each entry pairs summary notes, recommended resources, and follow-up practice.
Recommended Learning Path: 1. Identify gaps - Review the tables below to find topics you’re unsure about 2. Study fundamentals - Follow links to the relevant chapter sections 3. Test understanding - Take the linked quizzes to verify comprehension 4. Track progress - Return here to check off mastered topics
Best for: Self-assessment before exams, identifying prerequisite knowledge gaps, planning study sessions
Common Misconception: “Scoring low means I’m failing this course.”
Reality: Identifying knowledge gaps is the first step to mastery. Every expert started with gaps.
Key Points: - Scoring 3/10 on a quiz reveals 7 specific topics to study (that’s valuable data!) - Knowledge gaps are learning opportunities, not deficiencies - The best students actively seek out their weak spots - Discovery → Study → Practice → Mastery is the proven path
Remember: You can’t fix what you can’t see. Finding gaps is progress.
