If you have applied for a job lately — in tech or outside it — there is a decent chance you were asked to take a Wonderlic assessment. Maybe it was the classic 50 multiple-choice questions in 12 minutes. Maybe it was Wonderlic Select, which layers cognitive ability with personality and motivation sections and rolls them into a single job-fit score.
Either way, the format is brutal: roughly 14.4 seconds per question, no calculator, easy material under time pressure. The test is not really about whether you know calculus. It is about whether you can move fast, skip wisely, and stay calm when the clock is running.
And then you search for prep material online.
Most of what you find is a funnel: a few free sample questions, a paywall, ads, and upsells. That is fine if you want to buy a course. It is not fine if you just need honest practice before a screening round that might decide whether you get to the next interview.
So I built something different.
The problem is not just "study harder"
The Wonderlic has been used in hiring since 1936. You will see it in tech companies, healthcare, logistics, finance, and plenty of roles where employers want a short cognitive screen before investing more interview time.
The classic format — WPT-R — is 50 questions in 12 minutes. There are shorter variants like WPT-Q (30 questions / 8 minutes). Schools and nursing programs often use the SLE. Entry-level roles sometimes hit the WBST for basic verbal and math skills.
Then there is Wonderlic Select (formerly WonScore). That one is especially common in modern hiring pipelines:
- ~50 cognitive questions (same family as WPT-R)
- Personality section (Big Five traits)
- Motivation section (RIASEC / Holland codes)
- Roughly 35 minutes total, with a combined job-fit score at the end
For software engineers, the cognitive bar is often higher — many employers expect a 30+ on the 0–50 scale — and Select adds a twist people do not expect: you cannot pass on cognitive ability alone. The personality and motivation sections matter too.
That combination catches candidates off guard. You might be strong at LeetCode and still stumble because you never practiced timed verbal analogies, mental math without a calculator, or the "answer honestly but strategically" mindset Select expects on the non-cognitive sections.
Most free resources online do not help much. They are either generic IQ trivia, outdated blog posts, or lead-gen pages dressed up as prep sites.
What I shipped: Awesome Wonderlic
Awesome Wonderlic is a curated, ad-free, open-source prep pack for Wonderlic-style hiring assessments.
Everything in the repo is genuinely free:
- No ad-funded prep sites
- No freemium funnels
- No paid plans hiding behind a login wall
It is a dataset + curriculum + tooling project — not another timed quiz SaaS.
Content is dual-licensed:
- CC BY-SA 4.0 for docs, questions, and practice tests
- MIT for scripts and CI
What is inside the repo
150 original practice questions
The question bank has 150 original Wonderlic-style items across all six documented categories:
- Verbal reasoning
- Vocabulary
- Arithmetic
- Word problems
- Logic and patterns
- General knowledge
Each question lives in structured JSON with an answer key, difficulty rating (1–5), and a full explanation. The bank is validated in CI against a JSON Schema, so contributions stay consistent.
Exports are auto-generated to CSV, Markdown, and Anki TSV if you want flashcard drilling.
Full timed practice tests
There are two ready-to-run 50-question / 12-minute simulations with realistic category mix and difficulty curve:
Simulate real conditions: 12 minutes on a timer, no calculator, scratch paper only, no jumping around the test.
Need more? A Python script assembles unlimited randomized tests from the bank:
pip install -r scripts/requirements.txt
python scripts/build_practice_test.py --seed 7
Study guides and plans
The docs walk you through the parts most prep sites skip:
- Test types explained — WPT-R, WPT-Q, Select, SLE, WBST
- Scoring explained — the 0–50 scale, percentile intuition, role-based targets
- Question categories — the six families with worked examples
- Study guide and strategy — pacing, skip strategy, no-calculator tricks, error logs
- Test-day tips — a practical checklist
Structured study plans:
For engineers facing Select specifically:
- Wonderlic Select for software developers
- 14-day Select plan for software developers (plus a compressed 5-day variant)
One line from that guide worth repeating: the Wonderlic is not a knowledge test — it is a speed test over easy material. Select adds: you cannot pass on cognitive ability alone.
Curated external resources
The README also links vetted free material: official Wonderlic candidate FAQs and sample PDFs, the ICAR public cognitive item bank, open-source cognitive drill tools, and academic papers. The curation policy is strict — commercial prep sites are out of scope even when they offer free samples.
Start here (5 steps)
If the test is coming up, this is the fastest path in the repo:
- Read What is the Wonderlic? and identify which variant you are facing.
- Read How scoring works and set a realistic target for your role.
- Skim the six question categories with worked examples.
- Pick a study plan and follow it.
- Drill the question bank and take the full timed practice tests.
That is enough to go from "I have no idea what this test looks like" to "I have timed reps and a strategy" in an evening.
For builders: it is also a structured dataset
If you are the kind of person who learns by building, the repo gives you more than markdown pages:
- JSON Schema validation in CI (
data/schema/question.schema.json) - Export scripts for CSV / Markdown / Anki
- A practice-test generator with seed support for reproducible runs
- Python 3 tooling with a single dependency (
jsonschema)
You could fork it, build your own drill app, wire it into spaced repetition, or contribute new original questions that pass validation.
Why open source for this?
Hiring screens are already stressful. Prep material should not add a second paywall on top of the job search.
An open repo also means:
- Transparency — every question has an explanation you can inspect
- Community improvement — better wording, new items, translations of techniques
- No lock-in — export to Anki, print a practice test, or generate your own
Contributions are welcome: original questions, better explanations, vetted links, tooling improvements. Read CONTRIBUTING.md first — it documents the curation rules and the question authoring guide.

If you are preparing for a Wonderlic or Select screen, start with a timed practice test this week. Log your misses by category. Repeat under real conditions. That beats reading about the test for the tenth time.
If you are hiring and use these assessments, I hope this gives candidates a fairer shot at showing up prepared — without paying for ads first.

Have you run into Wonderlic or Select in a hiring process recently? What caught you off guard — the pacing, the personality section, or something else? I would love to hear what would make the repo more useful.
