I'm less keen on PBL in the first two years in particular because i don't think that it suits the type of information that you're being taught. The basic clinical sciences don't particularly lend themselves to being learned via pbl. That's what i feel anyway. I think that the sheer amount of content you have to cover and understand (which is ****ing huge) is much better delivered in a lecture based environment, more similar to school
We DO have PBLs but they're somewhat different to the way that universities like manchester/liverpool might do them.
Barts does offer intercalation
I'm not currently intercalating
You can intercalate in oral biology and this is by far the most sensible and common choice, but there are a wide range of other things such as pharmacology, neuroscience etc.
Intercalation is pretty rare in dentistry but very common in medicine. (i don't know any dentists who have intercalated, most of the medics i know want to though)
I don't know of any other universities that offer intercalation with the exception of kings college london.
Intercalation is pretty irrelevant to General practice. However, if you want to become an academic or go into research and become a lecturer or a professor etc. Then it suddenly starts to become much much more desirable. For specialisation, intercalation isn't really necessary as such, but it can't hurt.
My opinion is, if it's something you really want to do...or you really want to go into research. Then intercalate to your hearts content! It will probably also give you a bit of an edge in any interview or job application you go for...but not by a huge amount in my opinion.
The intercalation offered at barts right now have all been changed to one years MSc's rather than one year BSc's too...so i guess that's an added bonus?
