As a general rule, the 10th grade class newly admitteds are 30-40% of the number of 9th grade admits. Fewer entering-10th grade spots, fewer entering-10th grade applications.
In terms of admission at some of the most selective admissions schools, we notice the 10th grade admits often tend to have a very specific focus and high-level talent, i.e. dance, music, varsity athlete, visual arts. To the extent these schools admit well-rounded, “less pointy”, kids, this seems to happen more in the 9th grade class.
Glad you are re-applying, just make sure you have a nice, broad-range of schools that are not all ultra-low acceptance rate schools.
