On the contrary, assignments are designed to develop the skills of sound intellectual inquiry. Therefore, your task is to identify the skills that the assignment requires. Then you can begin to figure out how you can meet those objectives. If the objectives aren't clear, of course, you should ask the instructor to clarify the assignment. But the more you focus on those objectives, and developing your ability to meet the general standards of academic work, the more likely you are to do a good job on the assignment.
Anxiety can be a serious problem for students.
The energy that you spend being anxious takes away from the energy you have for thinking and learning. And the more anxious you are, the more likely you are to try to deal with it by escape and denial. If you find that you are procrastinating and not doing your work, it may be that you are so anxious about school and grades that avoidance seems the best answer. Of course, that is a vicious circle, because the more behind you get, the more anxious you become and the more you avoid doing your work. If anxiety seems to be seriously affecting your work, try to get some help from the University Counselor.
