Filtering duplicates

Hello. I'm working on a project that lists a student's ID number, name, Math classes taken, and grade per class. Many students have several rows of data because they have taken multiple Math courses. What I need to do is create a filter that removes the duplicate students and only shows the most recent Math class taken for each person. In other words, I'd like the followin example to list only John Smith's MTH-121 row, Suzie Que's MTH-04 row and Sallie Jane's MTH-121 row. Thanks in advance to whoever can help me out.

Example:

Student ID Student Name Math Course Grade
1111111 John Smith MTH-121 B
1111111 John Smith MTH-04 S
1111111 John Smith MTH-02 S
2222222 Suzie Que MTH-04 S
2222222 Suzie Que MTH-02 S
3333333 Sallie Jane MTH-121 A
