Updated April 2026 · Unbiased breakdown of what each platform actually does
JobTestPrep is one of the UK's largest aptitude test preparation platforms, operating since 1992. It offers employer-specific practice packs for hundreds of companies — Kenexa, Deloitte, HSBC, Goldman Sachs, and many more — along with general aptitude test practice. It charges per PrepPack, with most employer-specific packs costing £29–£79.
TestSolve is an AI-powered aptitude test practice tool. You practise with real-format questions, press F8, and receive the answer and reasoning on your phone. It's built for candidates who want instant, worked explanations while they practise, rather than working through a static answer key.
JobTestPrep is a practice test platform. You pay for access to a library of mock tests and written explanations designed to help you improve your skills before test day.

Depth of employer-specific content: JobTestPrep's PrepPacks contain genuinely detailed, employer-specific practice — EY packs built around Cappfinity's format packs mimicking Verify Interactive questions. The content quality is high and regularly updated.
Assessment centre preparation: JobTestPrep offers extensive materials for group exercises, in-tray exercises, case studies, and written exercises. If you have an assessment centre coming up, JTP's materials are excellent.
Interview preparation: Video interview guides, competency question banks, and STAR answer frameworks for specific employers. Useful for the later stages of any hiring process.
Institutional reputation: JobTestPrep has been operating since 1992 and has genuine track record and user reviews across thousands of assessments.
Instant, worked answers while you practise: Instead of waiting to look up a written explanation, TestSolve reads your practice question and shows the answer with step-by-step reasoning on your phone within seconds.
Cost adds up quickly: At £29–£79 per PrepPack, preparing for multiple employers — EY, Deloitte, KPMG, Barclays — costs £120–£300+. TestSolve's per-question pricing covers all employers and all question types.
Cheaper static practice too: If you'd rather work through full timed practice tests than use the live solver, TestSolve's SHL Style Practice Pack is $19.99 for 5 complete tests (120 questions, full answer keys) — less than a single JobTestPrep employer PrepPack, which covers only one company.
Questions don't match exactly: Despite best efforts, JTP practice questions are approximations of real tests, not the real tests themselves — the same is true of any third-party practice tool.
Both tools are practice aids for the period before your assessment. JobTestPrep gives you a large library of mock tests and written explanations to work through at your own pace. TestSolve gives you instant AI-generated answers and reasoning for whatever practice question is on your screen.
For candidates who want to build skills over time — who have weeks to prepare and want structured, expert-written material — JobTestPrep is a strong option. For candidates who want fast, worked explanations while practising a specific format, TestSolve is the more direct tool. Many candidates use both: build familiarity with JobTestPrep's question formats, and use TestSolve for quick, instant explanations along the way.
Use JobTestPrep in the weeks before your assessment to build familiarity with question formats. Use TestSolve alongside it whenever you want an instant worked explanation for a practice question. The combination helps you prepare more efficiently.
JobTestPrep's longevity — operating since 1992 — is a genuine differentiator in a market where many competitors are much newer operations. Three decades of building employer-specific PrepPacks means an enormous accumulated library covering hundreds of companies, refined over many hiring cycles as employers change providers, update formats, and adjust their process. For a candidate applying to a well-established employer with a long-standing, well-documented assessment process, this depth of accumulated, employer-specific detail is hard for a newer platform to match quickly, since it reflects years of tracking a specific company's actual test history rather than a single snapshot.
The tradeoff of this breadth is the per-PrepPack pricing model — at roughly £29–£79 per pack, candidates applying to multiple employers can find costs adding up quickly if they need several employer-specific packs across a job search, compared to a platform priced per practice session or per question rather than per employer.
A JobTestPrep PrepPack is built around one specific employer and provider combination, with practice questions, explanations, and often a personalised study plan tailored to exactly that assessment. This depth is genuinely valuable when you know precisely which employer and test you're facing and have the budget to invest in a dedicated pack for it. Where this model is less flexible is for candidates applying broadly across many employers, or facing an assessment from a provider that doesn't have a dedicated PrepPack built for that specific employer yet — in either case, a more general, real-time tool that adapts to whatever question format is actually on your screen, rather than requiring a pre-built pack matched to your exact employer, fills a gap the PrepPack model structurally can't.
Candidates applying to a single target employer with a confirmed test invitation are well served going directly to a matching JobTestPrep PrepPack if one exists — the employer-specific depth is worth the cost when you know exactly what you're preparing for. Candidates applying more broadly across many employers, especially earlier in a job search before specific invitations have arrived, often find it more cost-effective to build general format familiarity first — through free or lower-cost general practice — and reserve employer-specific spending for the employers that actually issue an invitation, rather than pre-purchasing packs for every company on a long application list. TestSolve's per-question pricing fits naturally into this broader-search phase, since it doesn't require committing to a specific employer or provider ahead of time.
A JobTestPrep PrepPack for a specific employer typically reflects publicly-known or candidate-reported details about which test provider and format that company has historically used, packaged into a structured study programme with matched practice questions. This is genuinely useful groundwork — understanding which provider you're likely to face, and what that provider's format generally looks like, removes a real source of uncertainty before you even start practising. It's worth being clear-eyed, though, that no legitimate third-party prep platform — JobTestPrep, TestSolve, or any competitor — has access to a live employer's actual proprietary item bank; what a PrepPack offers is a well-informed simulation built from historical patterns, not the literal real questions. Employers also periodically change providers or formats, so even a well-maintained PrepPack can occasionally lag a recent change, which is exactly why confirming details against your own actual invitation email remains worthwhile even after using a dedicated pack.
The strongest overall preparation, for candidates who can afford both, often combines a JobTestPrep PrepPack's structured, employer-informed practice sequence with a real-time answer tool for use during actual live practice or the test itself. The PrepPack builds targeted familiarity with the specific format you expect to face; the real-time tool handles the inevitable moments where the live question doesn't exactly match what you rehearsed, or where an employer has quietly updated their format since the PrepPack was last refreshed. Used together, each covers a gap the other one has by design — a structured library can't adapt to a surprise, and a real-time tool alone doesn't build the deeper pattern recognition a dedicated study sequence does over time. Neither tool fully substitutes for the other; together they cover a more complete range of what actually happens between the moment you receive a test invitation and the moment you sit the real thing.
JobTestPrep's three decades of accumulated, employer-specific depth makes it a strong choice when you know precisely which company and provider you're facing and have budget for a dedicated pack. TestSolve's flexible, per-question pricing and real-time approach makes it a strong choice when you're applying broadly, working against a tight timeline, or facing a live question that a pre-built pack simply can't anticipate. Choosing between them — or combining both — comes down to how well-defined your specific test situation already is.
Not necessarily. JobTestPrep is a practice platform with a large content library and written explanations. TestSolve is a practice tool that gives instant AI-generated answers and reasoning. Many candidates use both: JobTestPrep for structured practice, TestSolve for quick explanations.
Yes. TestSolve works on any browser-based test, including practice tests on JobTestPrep.
JobTestPrep packs cost 29-79 GBP per employer. TestSolve costs $14.99 for 30 questions across any employer or test provider, or $19.99 for a full 5-test SHL Style practice pack (120 questions) covering any employer.
Often yes — JobTestPrep's three decades in the business means an enormous accumulated library of employer-specific PrepPacks refined across many hiring cycles, which is genuinely valuable when you know exactly which employer and provider you're facing.
Buying a JobTestPrep PrepPack for every employer on a long application list gets expensive fast. TestSolve's per-question pricing doesn't require committing to a specific employer or provider ahead of time, which fits better into a broader-search phase.
JobTestPrep has historically offered a satisfaction guarantee on some packages, though exact terms vary by product and change over time — check the specific PrepPack's listing before purchasing. TestSolve's model sidesteps this question differently: the first solve is free, so you can evaluate accuracy on a real question before paying anything at all.
