Is it normal for you as an engineer to be good at math but a bad writer?

Answer 1

Yes, that is perfectly normal. The skills of English usage are different from those of mathematics and engineering. It is not unusual for a person to devote their attention to only one of these sets of skills, rather than both.

You do not necessarily have to be good at writing to be good at something else. Eventually, however, you will very likely be expected to explain something you've done to someone who doesn't understand the field, and being bad at writing will make such explanations a challenge. The best way to improve your writing skills is to A) take more writing courses than are required for graduation, and B) write as much as possible - essays, papers, articles, etc. Never resign yourself to being a bad writer. If you think or know you are, do what is necessary to remedy the situation.
