OMPT-E Explained: Syllabus, Difficulty, Test Example & Price

OMPT-E is the OMPT variant with the heaviest statistics and probability content. Here's the syllabus, difficulty level, a worked example, and pricing.

OMPT-E syllabus: what topics are covered

OMPT-E pairs the standard pre-calculus core (numbers, algebra, linear formulas and equations, systems of linear equations, quadratic equations, functions, exponential and logarithmic functions) with a full statistics track: descriptive statistics, probability, combinatorics, random variables, and common probability distributions. The exam is 40 questions in 120 minutes. See the full OMPT-E syllabus for the complete chapter list.

How difficult is OMPT-E?

OMPT-E is often underestimated by students who are comfortable with algebra but haven't studied probability and combinatorics recently — this half of the exam (roughly half the topic list) is usually where points are lost. Students typically need 100–120 hours of preparation, weighted more heavily toward probability distributions and combinatorics than the algebra section most students already know from OMPT-A-style content.

OMPT-E test example

*A bag contains 5 red and 3 blue balls. Two balls are drawn without replacement. What's the probability both are red?*

P(first red) = 5/8. P(second red | first red) = 4/7. So P(both red) = 5/8 × 4/7 = 20/56 = 5/14.

A distributions-style question: *Find the mean of a binomial distribution with n = 10, p = 0.4.* Mean = n × p = 10 × 0.4 = 4.

What do the real OMPT-E exam questions look like?

Expect a genuine mix — roughly half algebra/functions questions in the same style as OMPT-A, and half probability and statistics questions (combinatorics, distributions, expected value) that don't appear at all on OMPT-A, B, C, D, F, or G.

Is there an OMPT-E exam PDF?

No official exam PDF exists. Because the statistics half of OMPT-E is unique to this variant, a full mock exam covering both halves — algebra and probability — is the most realistic way to check you're not neglecting either side.
