Do you have any tips on how to properly revise

Yes, I'd recommend to go through things separate. First punctuation, go through with a highlighter and correct any spelling errors that you may have made. Next, go through and check your spelling. Reread your paragraphs and include information that was forgotten. Make sure you also get rid of information that you don't need. Good luck!

Reread your work, make any corrections if needed, for small words look for synonyms so your writing can look professional
