Don’t take this wrong, but 3 to 4 months in archery is a very short time, and if you don’t have some formal coaching, you can REALLY impact your ability to progress because so much in archery relies on muscle memory and repetition. You don’t want to be forming bad habits.
I’ve seen guys who are new to archery reach a high level of proficiency quickly because they got coaching and it gave them the proper foundation to build on.
By the same token, I’ve also seen guys who were new to archery but just watched YouTube videos and online forums… These guys plateau quickly because they have flaws in their form and shot process that have become limiting factors. For what it’s worth, bows are so good these days that it doesn’t take much to be pretty accurate. The problem is, that if you’re practicing the wrong stuff, you will be frustrated in getting accurate at longer distances because small flaws that you don’t know you have will cause inaccuracies at longer distances.
Online content is a huge asset to have available, but it cannot replace formal coaching, and you don’t want to have a dipshit like me critiquing your shot. I will say that even with coaching, archery can be a sometimes difficult thing to master and chasing accuracy or improvement through buying releases, new bows, sights, stabilizers, won’t make any difference - but getting good coaching absolutely will.
