Good morning, Mohammad:<br /><br />I hope you are well. Here is the edited document&nbsp;you requested.&nbsp;Although I was careful not to change your content, please proofread the document carefully. It sounds like an interesting and challenging course. I hope my suggestions&nbsp;help.<br /><br />If you have any questions, please send a message to me via Editor World. (I'll be away from the computer for 30 minutes. It's a lovely day here in Ontario, so I think I'll go for a walk.)<br /><br />Best wishes - George<br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status says 'unavailable', you can still reach me via Editor World.<br /><br />
