Best Free IT Certification Practice Test App in 2026
I tested 12 apps. Only 3 are actually worth your time. Here's my honest ranking.
I've spent the last month testing every major IT certification practice test app. Downloaded 12 of them. Tried the free tiers. Paid for a few. Burned through hundreds of practice questions across AWS, Azure, CISSP, and more.
And honestly? Most of them are garbage.
But three stood out. Here's my ranking, starting with the best.
1. ExamCert — Best Overall (and I'm not just saying that)
Look, I know this is an ExamCert blog. But I tested this app against the competition, and it genuinely won on almost every metric.
What Makes ExamCert Stand Out
- Actually free: Most apps bait-and-switch you with 10 free questions then demand $40. ExamCert gives you full practice tests for free.
- 30+ certifications covered: AWS, Azure, GCP, CISSP, CEH, CISM, PMP, and way more
- Realistic questions: Not scraped junk from forums. These feel like actual exam questions.
- Detailed explanations: Every answer comes with a thorough explanation—not just "the answer is B, trust us."
- No ads: Seriously. Try the app. Zero ads. Shockingly rare in "free" apps.
- Works offline: Download question sets and practice on the train/plane
What Could Be Better
- Premium features ($4.99 one-time) unlock progress tracking and more questions—but the free version is already solid
- UI feels a bit basic compared to flashy competitors (but honestly, who cares if the questions are good?)
Best for: Anyone studying for AWS, Azure, CISSP, or other major IT certs who wants quality practice without paying monthly subscriptions.
2. Pocket Prep — Best UI, Expensive
Pocket Prep has the prettiest interface. Smooth animations, clean design, gamification elements. It feels premium.
The Good
- Beautiful, intuitive UI that makes studying feel less painful
- Spaced repetition algorithm to optimize retention
- Community leaderboards for competitive types
- Covers tons of exams (IT, healthcare, finance, etc.)
The Bad
- Expensive: $19.99/month or $79.99/year for premium (ouch)
- Free version is useless: 10 questions per exam. That's it. Not enough to actually gauge readiness.
- Question quality varies: Some exams have great content, others feel rushed
- Subscription fatigue: Another monthly charge you'll forget to cancel
Best for: People who value UX over cost and don't mind paying $80/year for polished study tools.
3. PrepForCerts — Decent Budget Option
PrepForCerts is the middle ground. Not as good as ExamCert, not as expensive as Pocket Prep.
What It Does Well
- One-time purchase model ($9.99 per exam) instead of subscription
- Offline mode works reliably
- Covers niche certifications others skip
- Explanations are decent (not great, but workable)
What It Doesn't
- Question quality feels hit-or-miss—some are spot-on, others feel outdated
- No free tier—you pay upfront without knowing if the questions are good
- UI is clunky and dated (think 2018 Android app vibes)
Best for: People studying for less common certifications that ExamCert or Pocket Prep don't cover.
The Rest (Not Worth Your Time)
I tested 9 other apps. None are worth recommending. Here's why:
Quizlet: Great for flashcards, terrible for realistic exam prep. User-generated content quality is all over the place.
Exam Topics: Free questions sourced from dumps. Legally questionable, ethically worse, and you're just memorizing answers instead of learning.
Udemy Practice Tests: Bought a few. Quality varies wildly depending on the instructor. You're gambling $15-30 per test.
Whizlabs: Used to be great. Now overpriced ($99+/year) and question quality has declined.
Tutorials Dojo: Good for AWS specifically, but expensive ($15+ per practice test) and doesn't cover other vendors well.
What to Look for in a Practice Test App
Before downloading any app, check these boxes:
✅ Realistic Question Quality
The #1 factor. If questions don't match the actual exam format and difficulty, you're wasting time. Look for:
- Scenario-based questions (not just "what is X?")
- Multiple correct answers where you pick the BEST one
- Questions that test understanding, not memorization
✅ Detailed Explanations
Every wrong answer should teach you something. If the explanation is just "the correct answer is C," find a different app.
✅ Actually Free (or One-Time Payment)
I'm tired of monthly subscriptions. Give me a one-time purchase or a generous free tier. Apps that paywall after 10 questions are scams.
✅ Covers Your Exam
Obvious, but: make sure the app actually covers your certification. Some apps advertise "100+ exams!" but only have 20 questions for the one you need.
✅ Offline Mode
You shouldn't need Wi-Fi to study. Download questions and practice anywhere.
How I Actually Use Practice Test Apps
Here's my study workflow (works for AWS, Azure, CISSP, whatever):
Phase 1: Learn the material (weeks 1-4)
- Read official study guides or watch video courses
- Don't touch practice tests yet—build foundational knowledge first
Phase 2: Start practice questions (weeks 5-6)
- Take 20-30 questions per day on ExamCert
- Review EVERY wrong answer thoroughly
- Go back to study material for topics you're weak on
Phase 3: Full practice exams (weeks 7-8)
- Take full-length timed exams to simulate test day
- Aim for 80%+ before booking your real exam
- Focus review time on consistently missed topics
Common Mistakes People Make
Mistake #1: Only using practice tests
Practice tests don't teach—they assess. If you're scoring <60%, you need to go back and learn the material, not grind more questions.
Mistake #2: Memorizing answers
Taking the same practice test 5 times until you get 100%? Congrats, you've memorized question IDs, not concepts. Use multiple question sources.
Mistake #3: Ignoring explanations
If you get a question right, still read the explanation. You might've guessed correctly without actually understanding why.
My Final Recommendation
For most people studying IT certifications in 2026:
- Start with ExamCert: It's free, comprehensive, and the question quality is legitimately good.
- Supplement with official practice tests: Buy ONE official practice exam from the cert provider for final validation before test day.
- Skip the rest: You don't need 5 different apps. Pick one good source and go deep.
The best practice test app is the one you'll actually use consistently. ExamCert hits that sweet spot of quality + free + no-BS.

Test your knowledge with these exam-style practice questions covering key certification topics:
Question 1
Which Cisco IOS command displays the current running configuration on a router?
The 'show running-config' command displays the active configuration currently running in RAM. 'show startup-config' displays the saved configuration in NVRAM that will be loaded on reboot.
Question 2
A network administrator needs to prevent unauthorized devices from connecting to switch ports. Which security feature should be configured?
Port security limits the number of MAC addresses that can access a switch port and can take action (shutdown, restrict, protect) when violations occur. This prevents unauthorized devices from connecting.
Question 3
What is the default administrative distance for OSPF?
OSPF has a default administrative distance of 110. For comparison: Connected = 0, Static = 1, EIGRP = 90, RIP = 120. Lower AD values are preferred when multiple routing protocols advertise the same route.
Question 4
Which VLAN range is reserved and cannot be deleted or modified on Cisco switches?
VLANs 1002-1005 are reserved for legacy Token Ring and FDDI networks and cannot be deleted. VLAN 1 is the default VLAN and also cannot be deleted, but can be modified. Normal VLAN range is 1-1005, extended is 1006-4094.
Question 5
A router has two routes to the same destination: one with administrative distance 110 and metric 50, another with AD 90 and metric 100. Which route will be installed in the routing table?
Administrative distance (AD) is always evaluated before metric. Lower AD is preferred. Only when AD values are equal does the metric matter. In this case, AD 90 wins regardless of metric.
Question 6
Which IPv6 address type is used for communication between devices on the same subnet?
Link-local addresses (FE80::/10) are used for communication on the same local link/subnet. They are automatically configured on all IPv6-enabled interfaces and are not routable beyond the local segment.
Question 7
What is the purpose of the Spanning Tree Protocol (STP)?
STP prevents Layer 2 loops by blocking redundant paths in a switched network. It creates a loop-free logical topology by placing certain ports in a blocking state while maintaining redundancy for failover.
Question 8
Which command configures a Cisco switch port to operate as an access port in VLAN 10?
The correct command sequence is 'switchport mode access' to set the port to access mode, followed by 'switchport access vlan 10' to assign it to VLAN 10. Both commands are required.
Question 9
A network uses the subnet 192.168.10.0/26. How many usable host addresses are available?
A /26 subnet has 2^(32-26) = 64 total addresses. Subtracting the network address and broadcast address leaves 62 usable host addresses. Formula: 2^(host bits) - 2.
Question 10
Which protocol operates at the Network layer and is responsible for logical addressing and path determination?
IP operates at the Network layer (Layer 3) of the OSI model and is responsible for logical addressing (IP addresses) and routing/path determination. TCP is Layer 4, Ethernet is Layer 2, ARP bridges Layer 2 and 3.
FAQ: Practice Test App Questions
Yes, if the quality is high. ExamCert's free tier has enough questions to gauge readiness for most exams. But combine it with study guides/courses—don't rely solely on practice tests.
Only if you've exhausted free options and still need more practice. The official practice tests from cert providers (AWS, Microsoft, ISC2) are worth paying for—third-party premium subscriptions usually aren't.
Aim for 500-1000 unique questions for Associate-level certs, 1500-2000+ for Professional/Expert level. More importantly: review wrong answers thoroughly instead of just grinding volume.
No. They violate NDAs, hurt your learning, and many cert providers will ban you if caught. Use legitimate practice tests that teach concepts, not memorized answers.
