Chances of getting into Lawrenceville, Exeter, Andover, and Choate

Thank you sooo much! I just submitted all of my applications! I worked super hard on my essays, repeated my interview, had my alumni cousin write a personal letter of recommendation in addition to my app. However about the school, I am definitely a little worried. I know how unlikely it even is to get accepted in the first place, but if I were to be accepted I am worried about a recurring problem I seem to hear. I have seen alot of niche reviews and other people say how mentally taxing Lawrenceville is. I understand that the environment is extremely rigorous and competitive, but I have heard that the school is very “sink or swim” and does not provide any support to that rigor. Is this true? What is ur experience with this? I can hold my own and persevere through difficult situations well and have been fine in “sink or swim” environments before, but I truly thrive under at least a little academic support.
