Hi [USER=28506]@KBanana[/USER] and just to offer a quick response before [USER=36738]@Ram Sabaratnam[/USER] and [USER=2672]@Jessica Booker[/USER] come back to you: I think the answer is yes, provided that the course requires significant commitment of your time and efforts. If it takes less than 4-5 hours of study per week for you, I think that will mentioning it will likely not do you much harm, it won't add a lot of value either. If you dedicate around 10 hours or more, I would definitely mention it. On that point, I would also advise you to explicitly quantify your efforts both in terms of time commitments and regarding the level of proficiency you expect to attain.
