Nitrox class is necessary to take.
I'm hoping that this was meant as humor.
Moving on....get your own gear. The more you have to rent, the less often/likely you are to dive. When you have all your own gear, that boat dive suddenly costs less. I pay $100 for a 3 tank boat dive vs $150 for boat and rental gear. It's also easier to just pick up a tank or two at the rental shop with all your own gear already packed for the beach dives. Lastly, as was already mentioned, familiarity with your own gear leads to comfort in the water and more efficient handling of emergencies.
I had 65 dives when I completed rescue if that indicates how slowly I progressed. Now that I'm at that level I'll expedite through the rest. However, I also had great mentorship which has helped me learn more than any book or course.
