how to make a good thesis for my essay?
Im doing an essay on symbolism on life of pi. Im going to pick 3 different symbols not sure on what yet maybe animal symbolism. But I need a good thesis and how to relate back to it in my body paragraphs. I got 50% on ny last essay because I had a bad thesis.

There are 3 parts to every thesis statement.
1) The topic of your essay

2) Your opinion on the topic of your essay

3) The reasons for your opinion. (have 3 reasons why you think this.The objective of this is to persuade your readers to believe your opinion)

It should generally go near the end of your introduction paragraph.

Here’s an example.
Topic: Shopping at Walmart
Opinion: Everyone should shop at Walmart
1) Walmart has a variety
2) Walmart has a large inventory
3) Walmart has cheap prices

Now, let’s write the thesis statement. You can write your points at the end or beginning of the statement or in the next sentence.Choose whatever prompt you like the most to use in your paper.

Listed at the end of the sentence:
Everyone should shop at Walmart because they have a variety,large inventory, and cheap prices.

Listed at the beginning of the sentence:
The variety, large inventory, and cheap prices at Walmart are why everyone should shop there.

Points listed in the next sentence:
Everyone should shop at Walmart.They have a variety, large inventory, and cheap prices.

You should create a strong thesis statement. Don’t make it weak. Here’s characteristics of a strong thesis statement
• Answers a specific question
• Takes a distinct position on the topic
• Is debatable (a reasonable person could argue an alternative position)
• Appropriately focused for the page length of the assignment
• Allows your reader to anticipate the organization of your argument

Characteristics of a weak thesis statement. You should AVOID doing this.
• Vague: Raises an interesting topic or question but doesn’t specify an argument
• Offers plot summary, statement of fact, or obvious truths instead of an argument
• Offers opinion or conjecture rather than an argument (cannot be proven with textual evidence)
• Is too broad or too complex for the length of the paper
• Uses meaningful‐sounding words but doesn’t say anything
