I was on a holiday a few years ago when i started diving and found out that our Diveguide was also a recently passed DM, this gave me loads of confidence that, as a beginner, i would be in safe hands. The guy was a shockingly bad diver and was erratic and all over the place. At one point i thought he was having a mild seizure or sneezing fit underwater because he was twitching so much. Then he got us lost and we surfaced 800metres from the boat/shot line.
Back on the boat I'm gently quizzing the DG/DM about life in general and training etc, and he said, "10 weeks ago i could even swim confidently let alone scuba dive, I moved over to here when i left my office job and always wanted to be a scuba diver".
He had almost 100 dives in those 10 weeks. Quantity not Quality.
Please don't be like this guy. I hated diving with someone so new, Someone who had only slightly more overall time underwater than me, Someone i had no confidence in.
Thesedays i would be fine diving with someone so unpredictable because I'm confident and self-reliant, But back then as a noob i remember it shook me quite a bit.
