For this project, I had to write 5 clear, concise, well written sentences about what I've learned this week. Do these sentences look correct to you?

One of the most important lessons I have learned is to stay away from using vague or inappropriate words in my writing.

I have learned to use a dictionary, and a thesaurus, to improve my word usage in my writing.

I have learned why certain words are commonly confused, and strategies for finding and correcting them.

Spelling words correctly in my writing is paramount, therefore, I’ve learned that proofreading is imperative for correct spelling.

I have learned that the use of slang words should only take place in informal and casual situations.
