Hi guys! I just wanted to ask if any of you know of any good ways to get some more upper level linguistic courses online. I have an out of field undergraduate degree and just want to do everything I can to make my application more competitive. I have a lot of volunteering and shadowing hours, but I’m looking for courses that would be helpful and are offered online. I’ve looked at preparatory speech and language certificates that are offered in the states, have any of you completed one of these or know if they would be useful and considered in my application? Any suggestions are welcome! Thanks in advance.
