Online OCIA??

So I'm trying to convert from calvinism. I've been studying for about a year and im 100% I want to convert. My mom isn't happy and wouldn't let me do OCIA last fall so I will have to wait until next fall to start. Problem is I really don't want to wait that long. I need confession, I need baptism, and I need the Eucharist. I understand God gives grace to people like me who are unable to have those things at the moment even though I'm working toward them, but I need them for my own sanity and I don't think I can wait another year, especially for confession. I had a major slip up today and fell into sin I've been free of for months and started spiralling, then I saw an ad on instagram for CatechismClass.com which offers online OCIA classes. It said it is not intended to replace in-person OCIA, but at the discretion of the priest it may be accepted as valid. I have reached out to my priest and am waiting for his reply currently. I wanted to know if anyone else has done this?

also, lets say he approves and I start the course...would I have to be baptised and confirmed and received First Holy Communion at the Easter Vigil with other converts? Or can those things happen at anytime?

Please please please pray for me that this works out. I'm so ready to join and I'm so ready to get the sacraments and go to confession.
