You must pass the essay portion to pass the exam. The GED asks test-takers to write on a variety of subject matter.
Be organized. You should provide examples from the reading and explain how they connect to the main idea. As soon as you completely grasp the questions and once you have scribbled down some primary ideas, make an outline of the essay and follow that. With only 45 minutes to complete your essay, how will you be able to finish your piece?
This is how long you have to write your essay during the actual GED exam. Make sure you understand the issue and the position that each passage is taking.
