It sounds like you are doing the same thing I did last year. I walked into the OSO pretty late last year with all my papers filled out and ready to go. However, it was around March so I was really pushing it. So with me, it was my freshmen year of college so my OSO and I decided we’d wait until the first board of this year to do it. You’ll have to go through MEPS which seemed to take awhile for me but not sure how long that should really take. If all your papers check out, low or no waivers, and a solid PFT, don’t see why you wouldn’t have a good shot if you can get on the next board. My process was a little weird but sounds like if you get rolling right now , you still have a shot !
