Description

If you’re preparing for the Python PCEP Certified Entry-Level Programmer certification or a junior Python developer interview, taking these practice tests can boost your confidence and help you review Python fundamentals. These tests are fully aligned with the PCEP certification format, including the number and type of questions, time limit, and passing score. This makes them an excellent tool to evaluate your skills before the real exam. Besides assessing your knowledge, the tests also provide explanations for each question, which can help you comprehend the correct answer. However, note that these tests aren’t a comprehensive Python course, and they’re not intended for complete beginners. If you have no coding experience, it’s recommended to first take dedicated PCEP courses on Udemy. Each test in this course consists of 30 questions, and you have 45 minutes to complete it. The passing score is 70%.
