The order of the points in the blueprint should perfectly parallel the points in the essay. The phrasing of the points in the blueprint should all follow the same pattern. Students are also permitted to budget their time. Nothing stands out as a main idea. The sentence could easily confuse the reader, because the main focus is unclear.
Faulty parallelism is a grammatical error.
Flaws in the grammar of your thesis statement can be devastating to the overall effectiveness of the essay. A thesis statement amounts to nothing if the paper is not completely focused on that main point. Proper blueprinting facilitates the coherency of the thesis throughout the rest of the essay.
