thanks ethical PR, I'll check istock. It's not that I don't want to pay for the image, I'd more than happy to do so as they cost very little, it's the usual limitation of use that put me off. I haven't actually looked at istock, I'll see how they compare to others in terms of licencing.
Now to answer your question, I studied Marketing Management at University of Birmingham and I graduated in 2011. The degree hasn't been of much use, although I did enjoy the course, the marketing I learnt just didn't, and still doesn't have any workplace applicability. Luckily I was in a decent job (not degree related), but that enabled me to pay for further training in London, so I went ahead and learn property marketing, and now I do various jobs for letting agents (write marketing material, press releases, e-mail marketing). I knew that if I ever wanted to do marketing, I had to pick a niche.
Would I recommend a University marketing course to anyone? No. Which isn't to say that it doesn't help, or that some students haven't benefited from marketing degrees, I'm sure they have. But University doesn't teach you SEO, or how to successfully apply Social Media, or how to carry out a great PR campaign, how to write good marketing material, and even more importantly, how to sell a product or a service.
If you're friends son is looking for a fun course, not very challenging in terms of exams, that can be interesting at times (I learnt how an icecream maker made millions in sales by using pregnant nuns in his advertising), then by all means... to me though it felt like I would have learnt more sitting at home researching marketing material on Google.
In any case, best of luck to him, University costs 3 times more now than 2 years ago, so my advice is to pick a course carefully, not just because it's fun and easy to complete (which my course was).
