8. Punctuate correctly. Again, you can organize the principles of punctuation reviewed above into
a checklist for proofreading purposes. Furthermore, since you are in charge of the writing of the essay,
you can choose to avoid punctuation errors. If you are unsure how to punctuate a particular construction,
choose an alternative.
9. Avoid slang and low-level usage. The Writing Test is a test of standard written English, so you
should avoid slang and other low-level usage.
10. Write legibly. While it may not be literally true that neatness counts, it is almost certainly true
that an illegible essay will not receive a good grade. Even if you can’t do calligraphy, you should be able
to write legibly.

Identifying Sentence Errors
Identifying sentence error questions are the easiest of the three multiple-choice question types. You need
only determine whether a sentence contains an error; you do not have to figure out how to correct the
error. Here are the directions for identifying sentence errors:
Directions: Of the sentences in this part, some are correct and others contain errors of grammar,
usage, diction (choice of words), or idiom (correctness of expression). If the sentence contains an
error, the error is underlined and lettered. Assume that any part of the sentence that is not underlined
is correct and cannot be changed. In analyzing a sentence, keep in mind the requirements of stan-
dard written English.
If you find an error in a sentence, select the one underlined part that must be changed in order to
make the sentence correct and darken the corresponding space on your answer sheet. If the sentence
does not contain an error, darken space (E) on your answer sheet.
