Common mistakes to watch for
Mistake 1: Choosing by sound only
Some words sound the same or almost the same. Do not choose only by sound. Check meaning.
Example:
- Their, there, and they’re sound alike, but they do different jobs.
Mistake 2: Ignoring part of speech
Ask whether the sentence needs a noun, verb, adjective, or contraction.
Example:
- Advice is a noun.
- Advise is a verb.
Mistake 3: Reading too quickly
Many errors happen because the sentence is read too fast. Slow down and look for clues.
Mistake 4: Memorizing without examples
Rules help, but examples make the rule easier to remember.
Mistake 5: Thinking one quiz is enough
Confusing words become easier with repeated practice. Review the pairs you missed and try the quiz again later.
How to improve your score
Use this simple practice method:
- Write down the words you missed.
