Sure AOA maybe possible, it maybe outlined in your student handbook. Research is possible too sure, there are some ways to get published easily and other not so easy ways. I sense you are wanting to partake in multiple activities and will speed yourself thin.
Your focus should be on completing your coursework and clinical years without any more hiccups. Pass step 1 first attempt and do well on step2. If you can get off probation and get it removed completely that would be good too, the crap thing is sometimes state license forms, credentialaling and privileging applications as you about probation status during training years. They may still ask about why it took you an extra year for medical school.
Trust me that just the beginning of the questions they like to ask..
I believe you mentioned you know what you need to do different next time, which good but take a step back and reflect on the whole thing, You are smart enough to get into a US MD, I think you’ll be just fine going forward if you focus on what you need to do. It’s a long road ahead. Keep calm and carry on. Stay focused on what’s important going forward.
