What are my chances of getting into NSLC, ELSC, Harvard 2-week summer program, and SYMSP???

I am a sophomore with a 4.0 and took 1 honors class (no AP available) as a freshman, and two honors classes along with AP World History (only 1 available) as a sophomore. I am involved in Key Club and serve on the board as editor. I am also in the MESA (Math, Engineering, Science, Achievement) Club and won first place at regionals at Uni. of Santa Cruz. I was announced the most outstanding MESA member for 2017. I also got second place at the National University Poetry contest. I volunteer at my local Saint Agnes hospital and CAPS respectively. I am have also helped assist/coach my local basketball program/teams for youth. I’ve been a consistent volunteer at my local library since middle school as well… Other clubs I’m involved in are CSF, Green Club, Pre-med Club, GLOBE Project, and Ribbons of Hope…
What do you think my chances are of getting into:
-NSLC (National Student Leadership Conference) -preferably the medicine program
-ESLC (Envision scholarship leadership career) -also preferably med
-Harvard two-week summer program for high school
-Stanford Youth Medical Science Program

Does anybody else know any good programs or ways to spend my summer that I can use for enrichment. Also, previous alumni from these programs, any tips?!??!?!?!

Since you pay thousands of dollars to participate in these programs, you’ll probably get in. However, these programs aren’t as prestigious as they appear due to their price tag and wont really help in actual college admissions.
