Most people study for AWS certifications by watching videos and reading documentation. Research shows this has only 5-10% retention. There's a better way.
What Is Active Recall?
Active recall is a study technique where you actively try to remember information instead of passively reviewing it.
Passive Learning:
- Watching videos
- Reading notes
- Highlighting text
- Re-reading documentation
Active Recall:
- Answering practice questions
- Writing answers from memory
- Teaching concepts out loud
- Creating and reviewing flashcards
The Science
Studies show retention rates by learning method:
| Method | Retention Rate |
|---|---|
| Lecture/video | 5% |
| Reading | 10% |
| Audio/visual | 20% |
| Demonstration | 30% |
| Practice (active recall) | 75% |
| Teaching others | 90% |
Active recall forces your brain to retrieve information, strengthening the neural pathways. Passive review just gives you familiarity, not real knowledge.
Active Recall for AWS Certification
Method 1: Practice Questions First
Don't watch videos and then take practice tests. Flip it.
- Take a practice test on a topic BEFORE studying it
- Identify what you got wrong
- Study only those specific areas
- Retake practice questions
- Repeat
Why it works: You immediately discover your gaps and focus study time efficiently.
Method 2: Closed-Book Flashcards
Create flashcards for key concepts:
Front: "What are the S3 storage classes?" Back: Standard, Standard-IA, One Zone-IA, Intelligent-Tiering, Glacier Instant, Glacier Flexible, Glacier Deep Archive
How to use:
- Read the question
- Try to answer BEFORE flipping
- Check your answer
- Review missed cards more frequently
Method 3: Blurting Method
After studying a topic:
- Close all materials
- Write everything you remember about the topic
- Compare to your notes
- Study what you missed
- Repeat
Example for VPC: Write from memory: subnets, route tables, internet gateway, NAT gateway, security groups, NACLs, VPC peering...
Check: Did you remember Transit Gateway? VPC endpoints? Flow logs?
Method 4: Question Generation
After reading AWS documentation:
- Create your own exam questions
- Wait a day
- Answer your own questions
- Check against documentation
Example: Read about Lambda → Create questions:
- What's the max execution time for Lambda?
- What triggers can invoke Lambda?
- How does Lambda pricing work?
Method 5: Teach to Learn
Explain concepts out loud as if teaching someone:
- "Okay, so security groups are like a firewall for individual instances. They're stateful, which means if you allow traffic in, the return traffic is automatically allowed out..."
Can't explain it simply? You don't understand it well enough.
Active Recall Schedule for AWS
Week 1: Assessment
- Take full practice exam cold
- Identify weak domains
- Create flashcards for gaps
Week 2-3: Deep Learning
- Study weak areas with documentation
- Use blurting method after each section
- Answer practice questions daily
- Review flashcards (spaced repetition)
Week 4: Integration
- Take mock exams
- Analyze every wrong answer
- Teach concepts to imaginary audience
- Focus on persistent weak spots
Week 5: Final Prep
- Daily mock exams
- Rapid flashcard review
- Practice explaining scenarios out loud
Active Recall by AWS Topic
For Service Knowledge
Flashcards work best
Front: "When would you use SQS vs SNS?" Back: "SQS for decoupling, queue-based. SNS for pub/sub, multiple subscribers."
For Scenarios
Practice questions work best
Take scenario questions, cover the answers, think through your response, then check.
For Architectures
Drawing from memory works best
Draw a three-tier architecture from memory. Check against reference. Repeat.
For Procedures
Written recall works best
Write the steps to create a VPC from scratch. Compare to documentation.
Common Mistakes
Mistake 1: Recognition vs Recall
"I knew that!" when seeing the answer isn't the same as actually knowing it. Always try to recall BEFORE seeing options.
Mistake 2: Too Much Passive Review
Watching the same video twice doesn't double your learning. Use active recall instead.
Mistake 3: Skipping Difficult Topics
Active recall is hard, especially for topics you don't know. That's the point - the struggle creates memory.
Mistake 4: Not Spacing
Cramming active recall doesn't work. Space it out over days and weeks.
Tools for Active Recall
Flashcard Apps:
- Anki (free, spaced repetition)
- StudyTech (AI-generated based on your gaps)
- Quizlet (easy to use)
Practice Questions:
- StudyTech (personalized to your weak areas)
- Tutorials Dojo (high-quality static questions)
- AWS Official Practice Exams
Note-Taking:
- Notion (for blurting method)
- Obsidian (for linked notes)
- Paper (for drawing architectures)
StudyTech + Active Recall
StudyTech is built around active recall principles:
- AI Gap Assessment - Identifies what you need to recall
- Practice Questions - Active recall on your weak areas
- Spaced Repetition Flashcards - Optimal review timing
- Readiness Score - Shows when active recall is working
Instead of watching hours of video, you're actively practicing from day one.
Over 1,000 learners are using StudyTech's active recall approach to pass AWS certifications in 4-6 weeks. Start with a free gap assessment.
Summary
- Stop passive learning - Videos and reading alone don't work
- Use active recall - Practice questions, flashcards, blurting
- Test before studying - Find gaps first
- Space your practice - Regular review beats cramming
- Embrace the struggle - Difficulty means it's working
Active recall is harder than watching videos. That's why it works.
