OK M&TSI just ended yesterday. @sammng totally disagree with your earlier comment back in spring… farthest thing for “garbage” there could be. It was challenging and awesome! Obviously would have been better on campus for all the social reasons, but it was an exceptional experience, one of the best things I have ever done. The professors and TAs were amazing, projects were mind-blowing, and the other students (there were 95) are now my best friends! So glad I did it, worth every $. Good luck to everyone with all that is going on. And if you didnt get in as a junior, try again. It will be worth it! Also, Upenn admissions spoke to us and basically said that although it’s downplayed, M&TSI is definitely a hook for Penn admissions.
