How we review prep resources

We evaluate prep resources using practical, candidate-focused criteria:

  • relevance to the target assessment
  • clarity of the study path
  • quality of explanations
  • transparency around pricing and access
  • realism of marketing claims
  • fit for different candidate profiles

The goal is not to declare one product “best” for every candidate.

A prep resource that is useful for a named employment assessment may be a poor fit for a broad school exam, and a printed study guide may be less useful when the real test is timed, adaptive, or highly employer-specific.

When possible, our reviews separate:

  • who the product is best for;
  • what test families it appears to cover;
  • what candidates still need to verify before purchasing;
  • which alternatives may fit different budgets or study styles.

What these reviews cannot do

No prep product can guarantee a score, passing result, hiring outcome, or training success.

Prep also cannot replace official instructions from the employer, agency, test publisher, or candidate portal.

Before buying any prep product, confirm the exact test name, role, country, deadline, device requirements, retake policy, and whether the assessment is timed.

How to choose what to read first

Use the review hub this way:

CCAT, PI Cognitive, Wonderlic or mixed aptitude testing Best cognitive test prep
A comparison between major prep providers JobTestPrep vs Mometrix
A general product-level opinion JobTestPrep review
A book or course-style alternative Mometrix review

If your invitation names a specific provider or employer, prioritize the page that matches that test instead of choosing only by brand familiarity.
