A good GPA is always helpful in attaining good jobs. The counselor advices the students exactly what courses to take towards a certain degree. Some times students don't go to the counselors and select any courses, often barely to be a full time student. It is always a good idea to stay strictly within the requirement of the degree. Courses taken outside the requirement could result in delay of the graduation and waste of time and money.
All schools declare the requirement of a degree in their catalogues.
Depending upon the degree one wants to pursue, one can learn about the exact requirement. However, the courses should be balanced with some difficult and some hard ones. This can help students in devoting enough time towards studies and perform well. Some times students take all the difficult courses together and this brings their Grade Point Average down. Students who decide their major early normally finish under-graduation with 9 semesters some times even 8.
