• A FAQ with commonly asked questions

How we evaluated the platforms

When picking platforms, I looked for:

• Realism – Do questions feel like the actual exam (scenario length, plausible distractors, vendor terminology)?

• Explanations – Are answers justified with references, not just “B is correct”?

• Coverage – Do sets touch all current exam objectives/domains?

• Freshness – Evidence of recent updates aligned to 2024–2025 blueprints.

• Features – Timed mode, review mode, question flags, difficulty tags.

• Analytics – Per-domain scoring so you can target weak areas.

• Access friction – Sign-up required? Daily limits? Heavy ads?

• Mobile experience – Responsiveness or an app for on-the-go reps.

• Accessibility – Keyboard nav/alt text where applicable.

• Ethics – No leaked content; community uploads moderated.

Comparison matrix (features at a glance)

Pro tip: Print this table (or export to CSV) and mark the 3 platforms you’ll actually use. Depth beats dabbling everywhere.

How to use free practice tests the right way

1) Active recall first, then review

Start untimed with 20–30 questions to diagnose and force recall. Review only after you lock your answers.

2) Keep an error log (this is your superpower)

Track: Question → Concept → Why I missed it → Fix/Doc link → Next review date. Review your log 2–3 times per week.

3) Master by domain, not just overall score

Hitting 80% overall is nice—but if Identity & Access is 55%, that’s a risk. Target ≥80% in each domain.

4) Spaced repetition

Turn errors into flashcards (Anki/Quizlet). Review briefly daily; test weekly.

5) Pair with hands-on (cloud/dev/k8s)

If a question mentions IAM, build a quick policy. If Terraform backends confuse you, configure one. Doing beats reading.

6) Mock cadence

Weeks 1–2: short sets daily (20–30 Q).
Weeks 3–6: 1 full mock/week.
Final 2 weeks: 2 full mocks/week + targeted sprints on weak domains.

7) Benchmarks before you book

Aim for 75–85% on new practice sets (not repeats) across two different sources.

Ethics, NDA compliance & quality control

• Practice questions simulate objectives; dumps are prohibited. Using leaked content can void credentials and derail your learning.

• Cross-check questionable items against official exam objectives and vendor docs. If the explanation cannot cite an official source or credible whitepaper, treat with skepticism.

• Community platforms are fine for concepts and recall—not for memorizing suspicious question text.

Two free-heavy study plans you can steal

Plan A — Associate-level technical cert (8 weeks)

• Weeks 1–2: Official learning path + daily 15-Q checks (Microsoft Learn/AWS SB/GCP SB).

• Weeks 3–4: Domain-by-domain practice (FlashGenius free sets + vendor samples). Maintain an error log.

• Weeks 5–6: Add one weekly full mock from a mixed source; do hands-on labs for missed topics.

• Weeks 7–8: Two mocks/week; target ≥80% per domain; re-teach tough topics to a friend (or your rubber duck).

Plan B — PMP/management-style cert (6 weeks)

• Weeks 1–2: Read core guide + daily 25-Q scenario blocks (PMI/ATP samplers).

• Weeks 3–4: Weekly 120–180 Q mock; analyze why distractors are wrong; build a cheat sheet of people/process/business keywords.

• Weeks 5–6: Two mocks/week; flashcard only the “why” logic; book the exam once new mocks stabilize ≥80%.

FAQs

Are free practice tests enough to pass?
For fundamentals and some associate exams, yes—if you pair them with an error log and hands-on practice. For professional/specialty exams, you’ll usually need deeper banks or case studies.

How many practice questions should I do?
Think in blocks: ~500–800 total unique questions for associate level; ~1,000+ for professional/specialty. Focus on unique questions, not repeats.

How similar are free mocks to the real exam?
Official sources mirror tone best. Third-party sets vary—prioritize those with clear explanations referencing docs.

Do vendors offer official free practice?
Yes—Microsoft Learn, AWS Skill Builder (free tier), Google Cloud Skills Boost, CompTIA samples, and PMI/ATP samplers.

What score should I target before booking?
Consistent 75–85% on new sets across two sources, with no domain under 70%.

How do I spot low-quality questions?
Typos, no explanations, outdated service names, answers that contradict vendor docs, or obvious copy of “exam memory” posts.

Final takeaway (and your next step)

Free practice can get you 70–80% of the way. The last 20% comes from explanations, targeted domain sprints, and hands-on work. Pick three platforms from the list, start an error log today, and schedule your first full mock for two Sundays from now. Momentum beats perfection.
