Best psychometric test prep platforms compared (2026)

Last updated 26 August 2026 · Capply team

What actually matters in a prep platform

• Format accuracy: do the practice questions genuinely resemble what employers use?
• Feedback quality: a score alone teaches little; explanations and error patterns are where improvement comes from.
• Difficulty progression: fixed banks you exhaust versus practice that adapts as you improve.
• Coverage: numerical, verbal and logical at minimum; situational judgement and personality are increasingly part of real processes.
• Price model: one-off packs suit a single imminent test; subscriptions suit an application season with many employers.

The platforms

JobTestPrep

The longest-established name, with a very large catalogue of practice packs organised by test provider and by employer. If you know exactly which assessment you are facing and want a pack built to mimic that specific test, this catalogue is the deepest available. The trade-offs: packs are bought individually and costs stack up quickly across multiple employers, the interface shows its age, and practice is drawn from fixed banks rather than adapting to your level.

Best for: one imminent, known test from a specific provider.

AssessmentDay

A respected UK site offering a genuinely useful set of free practice tests with worked PDF solutions, plus paid packs for fuller access. The free tier is one of the best starting points available and the solutions are well explained. The trade-offs: the experience is closer to downloadable papers than an interactive training platform, there is no adaptive difficulty, and it does not extend beyond test practice into the rest of the application.

Best for: free practice papers and worked solutions when starting out.

Practice Aptitude Tests

Another strong UK option with free practice tests across many categories and helpful employer-specific guidance pages describing which assessments particular companies use. Paid access unlocks the full bank. The trade-offs are similar to AssessmentDay's: fixed question banks, limited feedback depth on the free tier, and a scope that ends at the test stage.

Best for: researching a specific employer's process alongside free practice.

Capply

The newest of the four, built by a UK student and taking a different approach on two fronts. First, practice is adaptive: numerical, verbal and logical tests adjust their difficulty to your performance, in four tiers, with AI feedback on where you stand and what to fix, plus situational judgement scored against an expert key, a workplace personality questionnaire and speeded reasoning sprints. Second, it covers the whole application rather than only the test stage: an AI CV checker that reviews and fully rewrites your CV, a cover letter builder that drafts from the actual job description, and a live feed of graduate roles pulled from employer job boards. It is subscription-based at £6.99 a month, cancel anytime. The trade-offs: it does not sell packs branded around individual named providers, its question banks are younger and smaller than JobTestPrep's catalogue, and there is no free practice tier.

Best for: an application season across multiple employers, when you want test prep and the CV, cover letter and job-hunting work handled in one place at a flat monthly price.

Side by side

How to choose

Start from your situation. One scary test next Tuesday from a known provider: buy the matching pack from JobTestPrep, or drill the free papers on AssessmentDay if budget matters. A full autumn of applications to many employers: a subscription you use daily beats buying packs per employer, and if you also need your CV and cover letters sorted, Capply is the only one of the four that covers those at all. Whichever you pick, the method matters more than the platform: short daily timed practice with honest review of every mistake, as covered in our psychometric test prep guide.
