I was really hoping Killexams would help me with studying for the Python certification. I was wrong. First of all, the code snippets in the test questions are not correctly formatted and can also contain weird special characters that don't belong. So you have to copy-paste the code into a text editor, correct and format it yourself. Then the code snippets is erroneous in some test questions but the answers don't acknowledge the code is wrong. Answers you select for some of the questions are correct but Killexams marks them as incorrect. Don't waste your money on Killexams.
