If you are not correcting the writing assignments on Google Drive, there is a very simple way to do so.
First download the paper on the desktop.
Save as pdf
Open the tools on pdf
Click on ‘Fill and Sign’
You will see a bunch of tools on the top of the page.
Underline, circle the points you want to highlight, add tick or cross wherever necessary.
Add text to give feedback.
Save and then email to your students.
Hope this will be helpful 🙂
Stay safe 🙂
