Hi Sean!
I do not know about the specific admissions process of TAMS. However, I can give you some general advice acquired through experience.
For the interview, I would recommend wearing a collared shirt, slacks, and dress shoes. For example, I wore a squared collared shirt with a solid cobalt, blue pullover on top, blue slacks, and some very nice penny loafers.
Be prepared to answer questions such as: “Why do you want to attend TAMS”, for this question, make sure to make it very unique for TAMS. A good starting point for this question that I used for all my schools is, “I believe X school is a truly international school and I believe I will not only grow academically but also perspectively as I will be surrounded by such a unique and diverse student body. I hope to learn how to be more accepting of others and simply be exposed to a myriad of different cultures, thus, allowing me to grow in ways that would be more difficult at another school. With this exceptional exposure to different people and cultures, I believe I will be able to make a magnificent change to our world community in X (state what you would like to do in the future. EX. Establish nonprofits, community service, career).”
Other questions you will most likely be asked include, “Describe a time where you found yourself in a difficult situation. How did you overcome it?”, with this question, make sure you also describe how you learned from this plight of yours, “What is your favorite and least favorite subject? Why?”, “What is your greatest strength and weakness? Why?”, “What activities do you do outside of school?”, “Describe your current school” MAKE SURE YOU SPEAK WELL ABOUT YOUR CURRENT SCHOOL, though, do explain what it is lacking.
Furthermore, if you have already submitted your application, there isn’t much you can do to increase your chances except for your interview. If you play sports, try to get in contact with the coaches and send them highlights and/or stats. On the TAMS website, they state that you must take the SAT Verbal and Mathematics sections. I would most definitely recommend buying Ivy Global’s SAT guide if you cannot afford a private tutor.
About spending a day with an ambassador, please do it. This is not to increase your chances, but rather to learn about the specific school in a much more personal level.
With your demonstrated interested in TAMS, through inquiring about the admissions process, asking for help, and asking very specific questions, I am absolutely certain you stand a magnificent chance of being accepted!
Best of luck,
Cristian
