An in-class essay is a timed essay written during class to test understanding of course material and writing skills. Proper preparation and time management are essential given the limited time frame of 1-2 hours compared to regular essays. Students should prepare by studying material in advance, getting sufficient rest, and using relaxation techniques. During the essay, students should understand the prompt, outline their response, write their essay in sections, and briefly proofread before submitting. Organization, a clear thesis statement, and incorporating relevant quotes and concepts can help students succeed on in-class essays.
