Oxford Continuing Education
Gain kudos with your local pharmacist whilst buying your Rennies by saying that you’ve studied Adverse Drug Reactions, Drug Interactions and Pharmacovigilance at Oxford University.
If you live a bit closer to Oxford, or have a bias towards the darker blue, then you will probably be attracted towards the Oxford continuing education offering (cf the Cambridge one).
The world really is your oyster with Oxford and so they have short courses including on archaeology, diplomacy, economics, art, languages, music, science and many, many more.
Bargain on about a couple of hundred pounds for a single day or around £1,000 for a five-day programme.
