I have my CAD exam tomorrow and I have completed reading ebook and also completed doing labs. I have some knowledge on ebook and I was going through mock tests from certyIQ pdf and I found out that many answers are mismatching or wrong when compared with other websites like examprepper or chatgpt/Gemini answers.

Could anybody please help me with this, which one should I follow now certyIQ pdf or examprepper or chatgpt answers??
