I am not sure why my answer was deleted, but you have a sponsor broker.
Best things to do is to speak with the broker for direction, ask about a mentor, shadow an experienced agent, have someone review your offer and ask questions.
If showing clients properties, have them ride with you so you can ask for feedback on properties shown, listen to what they are saying, adjust your property parameters and ask questions.
Asking questions is very important with the only wrong question being the one that is not asked.
If nothing else join a brokerage that offers support for new agents, it most likely will not be the one offering the highest commission split.
