Preparing for PPL Checkride

I'm planning to take my checkride in March and I wondering if any of you can give me some pointers, or feedback about your Oral experience.

I'm comfortable with the PTS and the flying components but did a self-study ground course (Sporty's) and don't have any idea on what questions will be asked. I've watched many Youtube videos, read the ASA Oral Prep book. Even though I know the topics covered in these books, I feel uneasy not knowing what the questions will be like.
