1. You cannot apply now. Each school starts accepting applications for the second year of study on October 1. If you are a junior, you can only submit it in October. Because the school currently only accepts students enrolling this year.
2. 2 letters of recommendation, which must be written on the school’s letterhead paper. You cannot use white paper or self-made inkjet A4 paper. Here you'd better use the school's official letterhead, which has the logo, phone number, address, etc. on it. And must be in a sealed school envelope. It has the recommender's signature.
