How to Choose: Decision Framework
Ask yourself these questions:
1. What's your learning style?
- Visual learner? → A Cloud Guru/Pluralsight, Udemy videos
- Learn by doing? → Practice exams (CertStud, Tutorials Dojo)
- Need hands-on labs? → Cloud Academy, A Cloud Guru
2. What certifications are you targeting?
- AWS only? → Tutorials Dojo is the gold standard
- Azure focus? → CertStud or Microsoft Learn
- Multi-cloud? → CertStud All Access
- Security (CISSP, etc.)? → CertStud
3. What's your budget?
- Free/Minimal → Official resources + CertStud free tier
- Moderate ($50-200/year) → CertStud (1 Cert $36/yr or All Access $96/yr)
- Generous ($300+/year) → A Cloud Guru + practice exams
4. How many certs do you plan to earn?
- 1-2 certifications → Individual purchases may work
- 3+ certifications → Subscription models save money
My Personal Recommendation
After testing all these platforms, here's my honest take:
For most people: Start with CertStud as your primary practice exam platform. The All Access plan at $96/year covers everything from AWS and Azure to CISSP and PMP. The clean interface and quality explanations make studying less painful.
Supplement with:
- Official resources (Microsoft Learn, AWS Skill Builder) for foundational knowledge
- Udemy courses from top instructors when you need video explanations
- Tutorials Dojo if you're specifically targeting AWS certifications
Avoid: Relying on ExamTopics or dump sites. Even if you pass, you won't actually learn the material—and that defeats the purpose of getting certified.
Final Thoughts
The certification prep market is crowded, but that's actually good news for learners. Competition drives quality up and prices down.
My advice? Don't overthink it. Pick a platform that fits your budget and learning style, then commit to consistent study. The best platform is the one you'll actually use.
