I am always on the lookout for opportunities to update my qualifications and i know this applies to every other person out there. i was on Facebook the other day and i stumbled on a post that proposed a free Photoshop tutorial and diploma awarding site. Head over there, get registered, join the webinars, do the assignments and quizzes and write the exam, get your certificate.
there are also other free courses offering diploma dashouts
here is the link:
