Independent reviews you can actually act on
Test prep is expensive — often $1,000–$2,000 a course. We exist to make that decision an informed one, with hands-on reviews that aren't for sale.
Katalyst Prep helps students find the best test prep resources for the LSAT, MCAT, GMAT, GRE, CFA, CPA and a dozen more exams. Test prep is a big, expensive decision — we exist to make it an informed one.
Our mission is simple: provide unbiased, in-depth reviews that help you score higher, so every student can choose the right course regardless of background or budget. Here’s exactly how we do that, and how we keep it honest.
Our review methodology
We buy and use the course
We pay for the courses ourselves and work through the actual material — lessons, question banks, practice tests — rather than rewriting marketing copy.
We test it like a student
We follow the study path, take the practice exams, and dig into the analytics dashboards to see what genuinely helps a score and what just looks good in a sales page.
We score on fixed criteria
Every course is rated on the same axes — curriculum quality, instruction, platform usability, support, and value — so ratings are comparable across providers.
We keep it current
Exams change. We re-review for the 2025 landscape (new LSAT, GMAT Focus, CPA Evolution, shorter GRE) and stamp every page with its last update.
How we stay unbiased
Katalyst Prep is reader-supported: when you buy through links on our site we may earn an affiliate commission, at no extra cost to you. That's it. Rankings are never sold, and an affiliate relationship never changes a score or a verdict — we disclose those partnerships on every page that contains them. We are not owned by, or affiliated with, any test maker or prep provider.
The team
Katalyst Prep is published by Ethereal Labs AB, an independent company. We're a small editorial team of researchers who analyze test prep courses full-time. Have a question about a review, or spotted something we got wrong? We want to hear it.
