Admissions is likely very busy this time of year. ALOs are doing evaluations of candidates. You could try reaching out, although I'm not sure what they could tell you.
Since you are a junior and the school year is only 1/4 way through, you should really try to get your course grades to As across the board and keep them that way. Towards the new year, focus on your SAT/ACT and get them as high as possible. You don't "boost up" ECAs. If you are involved in many many many ECAs just to check boxes, I would recommend you pick 2-4 that mean the most to you and try to get leadership positions in them. Do community service. But of course, don't forget to have fun!
Another thing, you started several threads all at one time. I'm not mod or admin, but I'm not sure if they would appreciate that. Personally, I would suggest you make one thread with all your questions. Just for future reference.
