It seems like you’re really eager to start applying for colleges. I was the same way! But, no colleges that i’m aware of open applications this early. The earliest one that I applied for opened in July. Some of them didn’t even open till around September.
Also, as a side note, this may not be applicable for you but if you’re applying to any schools other than prestigious schools you may want to wait a little later to apply. For example, I applied to all of my schools by october, but my GPA ended up going from a high 3.3 to a 3.5. I would have gotten more $$ in scholarships if I had waited to apply. Obviously this won’t work if your school’s deadlines are before that, or may not be necessary for you. Just thought i’d let you know!
