This course contains the use of artificial intelligence.

Here is what that means in practice, and why it is the reason to buy this one rather than another. Every question in these tests is built around a real snippet of Python. When the test was assembled, each snippet was executed by CPython, and the answer marked correct is the output the interpreter actually produced. A question whose stated answer disagreed with the interpreter could not be published, the build refuses it. That check is the whole point of the product.

If you have taken practice tests for this exam before, you already know the usual complaint. The explanation says one thing and Python does another, and you end up trusting nothing. That cannot happen here. Each explanation ends with the exact text the interpreter printed.

What is inside

Six full practice tests, 180 questions, forty minutes and a pass mark of 70 percent each, which are the conditions of the real exam.

Questions weighted the way the real PCEP-30-02 exam is weighted, following the syllabus published by the Python Institute. Block 1 on fundamentals is 18 percent of the exam, block 2 on control flow is 29, block 3 on collections is 25, and block 4 on functions and exceptions is 28. Each test follows those proportions rather than spreading questions evenly, so a score here means something about your score there.

Every question is tagged with its syllabus block. When you finish a test, the result screen shows which block cost you the marks, so you know what to revise instead of guessing.

Each answer, right or wrong, carries its own explanation. Not one comment for the question, one for every option, saying why that particular option is wrong and what confusion usually produces it.

How to use it

Sit a test under exam conditions first, forty minutes, no interpreter open. Read every explanation afterwards, including the ones you got right, because guessing correctly and knowing are not the same thing. Then run the snippets yourself. They are short on purpose and they all run on a plain Python 3 install with no libraries to fetch.

Who this is for

Candidates sitting the PCEP-30-02 exam who want to know whether they are ready, and Python beginners who want to find out what they only think they understand. You do not need any library, any framework or any prior certification.
