Re: grade this essay for me on the scale ged 0-4 and also check for punctuation error
1. Welcome to the forum.
2. When do you have to submit your piece to your teacher/tutor?
3. We quite like the words "Please" and "Thank you" on this forum. Your title sounds like an order.
4. In addition, your title doesn't follow the forum guidelines which ask you to include some words from your post in the title. A better title would have been "The major benefit of exercise" or similar.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
