Common Mistakes to Avoid

Example of mistake: “I want to boost my English skills in one year.”
Correct: “I want to improve my English skills over one year.” or “I want to strengthen my English skills.”

Example of mistake: “I want to upgrade my reading habit.”
Correct: “I want to improve my reading habit.” or “I want to refine my reading habit.”
