FInally ....all final exams are over .....

It is a good time to write something....... Because all the boring exams are over , expecially the botany lab test...... The test is very hard , I cannot understand some questions , so I think I would not get good grades on this subject ...But it's not important , I may not have to use these knowledge in my future career . What I want to ask is that "WHY SHOULD MEDICAL STUDENTS TAKE BOTANY COURSES?????"
