CLEP classes’ comparison

Let’s discuss how the different comparison points used in contrasting the different CLEP test topics against one another can help you have an idea of which CLEP exams are the hardest and easiest.


The number of CLEP exam questions can range anywhere from 44 to 140, all of which are multiple-choice questions, with the exception, of course, of writing sections — a couple of CLEP examinations, namely College Composition and Spanish with Writing, require test-takers to write up to 2 essays.

It goes without saying that the more multiple-choice questions are around, the more topics are covered by the CLEP class. So, in other words, you will have to read more during the CLEP test preparation phase.

Testing time

It’s not enough that you consider the number of questions a CLEP class has when determining whether it’s hard or easy — you should also take into account how many minutes test-takers have when trying to answer them correctly.

Take the number of questions for Calculus and Humanities, for instance.

Calculus has only 44 questions.

On the other hand, Humanities has a total of 140. But both CLEP examination topics have a testing time of 90 minutes.

Doing math, it means that every Calculus question needs to be answered in 2 minutes, while every Humanities question has to be answered in less than a minute only.

It doesn’t take a rocket scientist to know that, based on the number of minutes available for each question, Calculus is more difficult than Humanities as far as CLEP test topics go.

B-level score

According to the American Council on Education (ACE), which is a major coordinating agency for higher education institutions in the US, the recommended passing grade for CLEP examinations is B.

This means that CLEP test-takers should answer anywhere from 70% to 79% of all questions correctly for them to pass.

More importantly, they should get a B grade if they want to earn college credits.

A panel of college faculty who are teaching the equivalent course for CLEP examination topics, however, disagrees with ACE, which is why it has its own recommendation in terms of passing CLEP tests: the B-level credit-granting score.

Needless to say, test-takers, as far as the said team consisting of college faculty members is concerned, must correctly answer anywhere from 80% to 89% of all CLEP exam questions for them to pass as well as earn credits.

This means that if your top-choice institution’s CLEP credit policy follows the B-level approach, you will have to aim for a higher score.

But different colleges that accept CLEP can set the CLEP exam passing grade of their choosing.

And speaking of colleges where CLEP tests are honored, here’s a comprehensive post about institutions where you can take your CLEP scores — there are lots and lots of them, ranging from public schools to private liberal arts colleges.

Passing rate

The College Board, which is the non-profit organization that created and administers CLEP examinations, does not really publish the passing rate of CLEP tests — various sources, however, do.

Most of those who publish CLEP passing rates make public the rates for both civilian and military test-takers.

But the general rule of thumb is that one should consider the CLEP passing rate for military test-takers rather than civilian test-takers if the goal is to have a much more precise figure.

That’s because it usually takes more time for the military to come up with a report, which means that it can give a much better picture than civilian passing rates that come out frequently.

However, it’s not a good idea to establish the difficulty level of a CLEP class based solely on the passing rate, which can be affected by the knowledge and skills of the test-takers.

Take for example Spanish Language, which has a very high passing rate of 80% — of course, most students who would go for the said exam topic are very good with Spanish.

On the other hand, Financial Accounting has a low passing rate of 21% — having exceptional math skills is not enough as the discipline also requires critical thinking and organization skills.

CLEP Exam Difficulty Level Based on Passing Rates

Because the goal is to pass CLEP exams to earn college credits, it’s typically a good idea to consider the passing rate for each CLEP topic so that students may be able to register for tests wisely.

Naturally, as a general rule of thumb, the more test-takers pass a particular CLEP examination topic, the easier it’s likely to be.

Earlier, we compared all 34 CLEP exams using an assortment of comparison points.

In this part of the post, let’s determine which CLEP topics are the hardest and which ones are the easiest based solely on their passing rates — we will be using the 2020 military passing rate for each, in particular, for increased precision.

Just Before You Register for a CLEP Exam

It goes without saying that opting for something that you can answer confidently can increase your chances of passing and, more importantly, earning college credits.

But other than determining which CLEP exams can win you credits, it’s also important to determine whether or not your top-choice institution accepts CLEP scores — attending one that does not honor CLEP tests, of course, makes taking a CLEP exam totally pointless.

Prior to registering, research the CLEP exam you like to take and the school you want to go to.
