LZ, don't be panic; it does not help anything. Be mature, and calm
down in the first place. To your question 2, you need to actively contact
school, and see if additional recommendation is acceptable and encouraged.
Plus, I recommend you to do a campus visit - this is definitely not
additional material, but additional effort. You wanna show that you really
love the school, and would like to have a first-hand touch. There are tons
of things to do while on campus - attending classes, chatting with your
targetted club leaders, and probably sharing your experiences and goals
with relevant professors. Good luck! |
