You can write it in, but you must have the corresponding certificate. Don't write without a certificate. In addition, it is best to scan and save all award-winning certificates in a picture format of no more than 80K/ piece, and make attachments separately, and don't post them at the back of your resume. If you have a good internship experience in college, you can also write it in. You should write about what you did, what role you played and what you learned. Don't simply write time, unit and position.
