From the way you've described your essay, it looks more like an expository essay.

Writing an introduction to an essay can be a challenging task, but with the right approach, you can make it engaging and informative. Here are some steps you can follow to write an introduction for your essay about your experience in a chaotic class and how it led to an early graduation:

1. Start with a captivating hook: Begin your introduction with an attention-grabbing statement or an intriguing question related to your topic. For instance, you could say: "Imagine stepping into a classroom where chaos reigns, the noise level is deafening, and any hopes of learning seem like a distant dream."

2. Provide a brief background: Give your readers some context about the chaotic class you were in. Provide a general overview of the problems you encountered and the overall out-of-control atmosphere. This will help to set the stage for your essay and engage your readers.

3. Share your personal experience: Transition from the general background information to your personal experience in that class. Describe the challenges you faced, the difficulties in maintaining focus and concentration, and any negative effects it had on your educational journey. This will help your readers empathize with your situation.

4. Highlight the turning point: This is a crucial part of your introduction. Explain how, amidst the chaos, you were given an opportunity to graduate early. Highlight the moment or series of events that made you realize the importance of seizing this chance and how it impacted your decision to pursue an accelerated path to graduation.

5. Introduce your essay's focus: Finally, end your introduction with a clear statement of the main theme or purpose of your essay. Explain that your essay will explore the lessons you learned from the out-of-control class and how it ultimately shaped your academic journey towards early graduation.

Remember, the introduction sets the tone for your essay and should make the readers interested in reading further. It should be concise, engaging, and provide a clear overview of what your essay will be about.
