Expert writing Tips

Best practice

Always use "confident in" instead of "confident on". This ensures grammatical correctness and clarity in your writing. For example, say "I am confident in my ability to succeed" rather than "I am confident on my ability to succeed".

Common error

Avoid using "on" after "confident". The correct preposition is "in". Using "on" can make your writing sound awkward or ungrammatical.
