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 — SHL, 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 solver. You take your real assessment, press F8 on any question, and receive the answer on your phone in a few seconds. TestSolve does not require you to study or practise beforehand — it solves questions in real time during your actual test.
JobTestPrep is a practice test platform. You pay for access to a library of mock tests designed to help you improve your skills before test day. You study, practise, and hope that the practice transfers to your actual performance. JobTestPrep has no role on the day of the actual test.

Depth of employer-specific content: JobTestPrep's PrepPacks contain genuinely detailed, employer-specific practice — EY packs built around Cappfinity's format, SHL 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.
Practice doesn't guarantee performance: Research on test score improvement through practice shows high variability. Candidates who practise on JobTestPrep improve, on average, by 5–15 percentile points — not guaranteed. TestSolve's AI doesn't rely on your ability to improve; it provides the correct answer directly.
Cost adds up quickly: At £29–£79 per PrepPack, preparing for multiple employers — EY, Deloitte, KPMG, Barclays — costs £120–£300+. TestSolve's flat monthly subscription covers all employers and all question types.
No role on test day: After spending £60 on a practice pack, you still sit the actual test alone, under time pressure, with full responsibility for answering correctly. TestSolve is present with you during the test.
Questions don't match exactly: Despite best efforts, JTP practice questions are approximations of real tests, not the real tests themselves. For SHL Verify Interactive specifically — which uses drag-and-drop rather than multiple choice — practice packs capture the concept but not the exact interaction format.
Both tools serve different moments in the hiring process. JobTestPrep is pre-test preparation. TestSolve is test-day performance. JobTestPrep cannot help you on test day. TestSolve cannot replace the confidence that comes from preparation.
For candidates who want to improve their aptitude test skills over time — who have weeks to prepare and genuinely enjoy sharpening their quantitative reasoning — JobTestPrep is a legitimate option. For candidates who have an assessment coming up in 24–72 hours, or who simply want to maximise their score on the day rather than rely on uncertain practice transfer, TestSolve is the more direct solution. Many candidates use both: practice with JobTestPrep to build familiarity with question formats, and use TestSolve during the actual test to ensure correct answers.
Use JobTestPrep 1-2 weeks before your assessment to build familiarity with question formats. On test day, use TestSolve to get AI-powered answers delivered to your phone. The combination maximises your chances of passing.
No. JobTestPrep is a practice platform you use before your test to build skills. TestSolve is a real-time solver you use during the actual assessment. Many candidates use both: practise with JobTestPrep, then use TestSolve on test day.
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.
