The GMAT tests only a limited number of grammar error types. Therefore, you only need to learn a handful of rules – you don’t need to master every grammatical and stylistic rule of Standard Written English to do well on the GMAT.

Seven Types of Errors in Sentence Correction

  1. Subject-Verb Agreement
  2. Modifiers
  3. Parallelism
  4. Pronoun Agreement
  5. Verb Time Sequences
  6. Comparisons
  7. Idioms
