Units

1. UNIT 01

   Parts of speech

   Every word in a sentence plays a role. Knowing the parts of speech makes every other grammar rule easier.
2. UNIT 02

   Sentence structure

   A complete sentence needs a subject and a verb and must express a complete thought. Fixing fragments and run-ons is one of the most tested skills.
3. UNIT 03

   Agreement

   Verbs must match their subjects in number, and pronouns must match the nouns they replace.
4. UNIT 04

   Punctuation

   Punctuation tells readers how to group ideas. Most tested rules involve commas, semicolons, colons and apostrophes.
5. UNIT 05

   Commonly confused words

   Many errors come from words that sound alike. A quick test for each pair fixes most mistakes.
6. UNIT 06

   Modifiers, parallelism and verb tense

   Clear sentences put modifiers next to what they describe, keep items in a series in the same form, and don't jump between tenses.
