Start with the type of certificate you need
The first split is the kind of credential itself, because the providers here do not sit in the same field. Marisa Peer lists professional coaching certification, delivered both online and in person, with course hours of 300 hours and a required practicum, which is the placement-style supervised practice that separates a coaching certificate from a self-study course. CrackCerts sits in IT, listed as online only. Testprep Training also lists IT, with exams spanning gmat, gre and pmp.
So a coaching buyer and an IT buyer are not comparing the same product. A coaching course with supervised practice hours and an IT exam-prep bundle share a delivery format but little else. Check the rankings for fitness, IT and coaching certifications to see which category each option actually belongs to before you compare prices side by side.
Entry price tells you little on its own
The cheapest listed price across this set is CrackCerts at $9.99, with Marisa Peer starting at $7. Those are entry points, not what most buyers pay for a full study package. Marisa Peer's all-access audio pass is listed at $19 per month and $149 per year, so the annual rate is the one to compare against an annual plan elsewhere.
Testprep Training does not publish a single starting figure, so its pricing runs through bundles instead. Its practice exams are priced individually, with a free practice test alongside paid ones, and course packs sold in Pro Plans bundles that get cheaper as you buy more courses at once. Across the whole database, listed entry prices span €8.76 to €17,432.74, and listed course hours span 4 to 500 hours. Read those spans as the outside edges of what the market contains, not as a promise about any one provider.
The practical rule: price per hour of study or per practice exam, not per course page.
Study hours and assessment count
Marisa Peer publishes course hours of 300 hours, which is one of the larger figures in this comparison. Testprep Training publishes 45 hours for one of its Microsoft Azure Administrator Associate courses and lists 200 courses in total, with assessments included. CrackCerts publishes neither a course count nor a total of hours in this set, which leaves you comparing against its practice-test pages rather than a study volume.
A provider that lists assessments tells you how much material exists to attempt. A provider that lists hours tells you how much scheduled material exists to work through. Those answer different questions, and a long hour count says nothing about how many of those hours are supervised or assessed. Check the CrackCerts review and the Testprep Training review side by side on this point, because only one of them publishes an assessment count.
What is actually included in the fee
Exam fees are the quiet cost that flips a cheap price into an expensive one. Neither CrackCerts nor Testprep Training includes the exam fee in the price of the listed material, so budget for the vendor exam separately in both cases. Marisa Peer's free tier means a free option exists to test the platform before you pay.
Delivery format narrows this further. CrackCerts and Testprep Training are online only, while Marisa Peer supports online and in-person delivery. If your certification requires in-person practice hours, online-only providers drop out of the running no matter what their entry price looks like.
Refund and guarantee terms are not interchangeable
Marisa Peer offers a money-backed window of 14 days, and CrackCerts offers 30 days, so the longer window belongs to CrackCerts. Neither promise is the same thing as a pass guarantee, and a refund window only protects the money you already spent.
Testprep Training's guarantee is conditional and the conditions matter: a refund has to be started shortly after a result arrives and within a limited window from purchase, with proof of failure, and it is returned less a small processing fee. Read those terms directly on the provider's terms page rather than assuming the refund window figure means the same promise it does elsewhere. That difference alone can decide between two providers with identical course pricing.
Support, job support and where the provider sits
Tutor support is offered by both CrackCerts and Marisa Peer, so a named point of contact is not a differentiator between those two. The channels are. Marisa Peer supports email, phone and a help centre, while CrackCerts offers email and a community. A phone line is worth more to some buyers than a large community, and worth less to others.
Job support is where the coaching and IT options split sharply: Marisa Peer offers it, CrackCerts does not. Testprep Training does not list it either, though it is the only provider here to publish a course catalogue that includes gmat, gre and pmp, which matters if you want one supplier across several exams.
Headquarters location also shapes what you can expect. Marisa Peer is registered in GB under MORE THAN ENOUGH LTD, and its platform type is listed as curated rather than an open catalogue, so you take what is selected for you. CrackCerts and Testprep Training are both registered in IN, and Marisa Peer allows offline download. Timing and payment terms can follow from where a provider is based and how it is registered.
A short order of operations
Confirm the credential type matches your field, then confirm delivery format fits your schedule and any in-person requirement. Next, price the study material and the vendor exam as two separate line items, and convert both into an hourly or per-exam figure. After that, read each refund or guarantee term closely, since the windows and conditions differ. Finish by checking what support you would actually use, then read the Marisa Peer review or the Testprep Training review for whichever option survived those steps.
The rankings for fitness, IT and coaching certifications are the quickest way to narrow the field first, since they group the options by category rather than by price.
