Expert writing Tips
Best practice
When using "busy with classes", ensure the context clearly indicates what type of classes are being referred to. Specify the subject or level if necessary for clarity. For example, instead of just saying "I'm busy with classes," say "I'm busy with my calculus and history classes."
Common error
Avoid using "busy with classes" when the context doesn't clearly indicate that you're referring to academic coursework. If you mean something else, such as cooking classes or art classes, be specific: "I'm busy with cooking classes," rather than the more ambiguous "busy with classes".
