Expert writing Tips

Best practice

Always use "be competent in" or "be competent at" instead of "be competent of". For example: "She is competent in data analysis".

Common error

Avoid using "of" after "competent". The correct prepositions are "in" or "at". A common mistake is saying "He is competent of handling the task", which should be "He is competent in handling the task" or "He is competent at handling the task".
