No. According to article 4 of Senate Practice Fundamentals for DMP, students who are in their third year cannot apply for the DMP even if they had not taken any course from the third year.

Yes, you can apply for it.

First and foremost, try to keep your GPA as high as possible. Students who have completed two semesters (three semesters for irregular students) in their undergraduate program (excluding preparatory courses) and have achieved a total credit score between 30-59.99 (2nd year) can apply to the 3rd semester. Students who have completed four semesters (five semesters for irregular students) in their undergraduate program (excluding preparatory courses) and have achieved a total credit score between 60-94.99 (3rd year) can apply to the 5th semester. Applications from students who have achieved credit scores outside these ranges will not be considered. Furthermore, if your first major program has elective courses in its first and second years, be sure to choose equivalent courses in your second major. This will reduce the number of credits you need to take in your second major. Reviewing the double major program for your first major students will guide you in this matter. If a Double Major Program for the Second Major has not yet been prepared, it would be helpful to review the four-year curriculum (including elective courses) of the Second Major and consult with the Double Major advisor for the Second Major.

If you took and passed the course, apply to the related Faculty by a petition for the exemption of the course. You can be exempted from the course if its content is found adequately equivalent.
