Send your portfolio task document to a designated classmate by e-mail. You will also receive your classmate's work. Read the document thoroughly and provide your classmate with a numerical and verbal feedback (see the template instructions). When you are ready with the feedback, send the commented document to your classmate by e-mail again. 

Please take into consideration, that you all need to update your portfolio tasks according to the received feedback. Therefore make a mutual agreement and exchange the commented documents well in advance.
