When I started, I had no idea where to begin. What really helped was ITExamsTopics I went through their practice questions daily, not to memorize but to understand the reasoning. By exam day, nothing felt unfamiliar.
My advice don't just read the docs. After each topic, test yourself immediately. I cleared it first attempt in about three weeks. Totally doable if you stay consistent.
Anyone with questions, feel free to ask below happy to help.
