The best GED mock exam choice is usually GED Testing Service for final score prediction, and Kaplan for longer study practice. GED Testing Service offers the official GED Ready practice test, so its scoring and question style sit closest to the real exam. Kaplan gives students more drills, explanations, and study structure, which helps before the final check.
TLDR: A student who has three weeks left should use Kaplan first, then take the official GED Ready test from GED Testing Service. For example, a learner scoring 145 on Kaplan math might use two weeks of targeted review, then confirm readiness with a GED Ready score of 155 or higher. GED Testing Service is better for accuracy; Kaplan is better for volume and guided practice. Most students benefit from using both, but not at the same time.
GED Testing Service vs Kaplan: The quick difference
GED Testing Service creates the actual GED exam. Its practice product, GED Ready, is the official mock exam for each subject. Kaplan is a major test prep publisher that sells GED books, online practice, and study plans.
The difference is simple:
- GED Testing Service is best for checking if a student is likely to pass.
- Kaplan is best for learning, drilling, and building confidence over time.
The catch is that official practice tests are shorter and cost money per subject. Kaplan often gives more practice for the price, but its score estimates may not feel as exact. That can be annoying when a student wants a clear yes or no before booking the real test.
What GED Testing Service does better
GED Testing Service has the strongest claim to accuracy. Since it designs the real GED test, its practice questions match the official style more closely. The GED Ready test also gives a useful score range and a message such as “Likely to Pass” or “Not Likely to Pass.”
That matters. A student does not need vague encouragement one week before test day. The student needs a reliable signal.
GED Ready is also useful because it mirrors the official feel. The screen, timing, question types, and scoring logic feel familiar. That reduces stress on test day. For many adult learners, that alone is worth the fee.
GED Testing Service works best for:
- Final readiness checks
- Students close to passing
- Practice under official-style timing
- Finding weak subjects before paying for the real exam
- Reducing test-day surprise
Its main flaw is limited practice depth. A student cannot treat GED Ready as a full course. It shows where the student stands, but it does not teach every missing skill in detail. If the score is low, the student still needs lessons, examples, and repeat practice.
What Kaplan does better
Kaplan is stronger as a study system. Its GED materials usually include full-length practice tests, subject reviews, skill drills, answer explanations, and test tips. This helps students who are not quite ready yet.
Kaplan also explains mistakes better. If a learner misses a math problem involving slope, Kaplan may show the steps and point back to the related lesson. That is helpful. GED Ready may report weakness, but it will not always teach the topic deeply.
Honestly, it feels like Kaplan sometimes asks a student to do extra clicking, reading, or page flipping before reaching the exact fix. Still, the extra material has value. A student who needs repetition will get more of it there.
Kaplan works best for:
- Students starting GED prep from scratch
- People who need explanations after wrong answers
- Longer study plans of four to twelve weeks
- Reviewing math, science, social studies, and language arts
- Building stamina with longer practice sets
Kaplan’s weakness is prediction. Its tests can be close, but they are not official. A Kaplan passing score should be treated as a good sign, not a guarantee.
Score accuracy and readiness
For score prediction, GED Testing Service wins. The GED Ready score is the clearest estimate because it comes from the official source. If a student scores safely above the passing mark on GED Ready, that is a strong green light.
The GED passing score is 145 per subject. Still, many tutors prefer a comfort range. A student who scores 145 exactly may be at risk if nerves, timing, or one hard passage gets in the way. A GED Ready score of 155 or higher often feels safer.
Kaplan helps build that cushion. For example, if a student gets 52% on a Kaplan math practice test, then improves to 68% after two weeks, that trend matters. It shows growth. But the student should still confirm with GED Ready before scheduling the real exam.
Question quality and test feel
GED Testing Service has the edge in realism. The wording, tools, charts, drag items, calculator setup, and reading passages feel closer to the real test. That makes it the better mock exam for the final stretch.
Kaplan has the edge in variety. Its materials may include more questions across more subtopics. Some questions can feel a little harder, easier, or more textbook-like than the real test. That is not always bad. Extra challenge can expose gaps. But it can also make a student worry too much.
For language arts, students should pay close attention to reading length and timing. For math, calculator use and formula practice matter. For science and social studies, data charts and short evidence questions appear often. Both products cover these areas, but GED Testing Service feels more exact.
Cost and value
GED Ready tests are usually bought by subject. That means a student may pay separately for math, science, social studies, and language arts. The total cost can add up.
Kaplan often offers better value for bulk practice. A book or online program can cover all subjects at once. This makes Kaplan useful for students on a tight budget who need weeks of prep before taking any official mock exam.
A practical budget plan looks like this:
- Start with Kaplan for broad review and practice.
- Track scores by subject for two to four weeks.
- Use GED Ready only when scores suggest the student is close.
- Schedule the real GED after a strong official practice score.
This avoids wasting official practice attempts too early. Expect to waste time on retakes if a student uses GED Ready before studying the basics.
Best choice by student type
The right choice depends on the student’s current level. A student who has already studied and only needs a final check should pick GED Testing Service. A student who feels rusty, especially in math or writing, should begin with Kaplan.
| Student goal | Better option |
|---|---|
| Predict real GED score | GED Testing Service |
| Study from the beginning | Kaplan |
| Get detailed explanations | Kaplan |
| Practice official test format | GED Testing Service |
| Prep on a wider budget plan | Kaplan first, GED Ready later |
Final recommendation
Kaplan should be used as the training ground. GED Testing Service should be used as the final checkpoint. That mix gives students both practice volume and official score confidence.
A simple study path works well. The student studies with Kaplan until practice scores rise above the passing range. Then the student takes GED Ready in that subject. If the GED Ready result says Likely to Pass, the student schedules the real test. If not, the student returns to Kaplan for targeted review.
This method keeps practice organized. It also lowers the chance of paying for the real GED too soon.

Yes, some students can. Still, taking GED Ready before the real test is a safer final check.
When should a student take the GED Ready test?
A student should take it after studying, not at the start. A good time is when Kaplan scores show steady passing-level performance.
Which option is better for math?
Kaplan is often better for learning math steps and practicing weak skills. GED Testing Service is better for checking if those skills are ready for the real math test.
Should students use both GED Testing Service and Kaplan?
Yes. Kaplan first, GED Ready second is the strongest plan for most GED students.
