Expert writing Tips

Best practice

Avoid using "and then doing" in formal writing. Opt for grammatically correct alternatives like "and then I did", "and then proceeded to do", or "and then did".

Common error

A frequent mistake is using "doing" after "and then" without a proper auxiliary verb or subject. Remember to include a subject and a conjugated verb to form a complete clause. For example, instead of "I finished my homework and then doing the dishes", write "I finished my homework, and then I did the dishes."
