Yes you can still get the JSA but it's dependent upon whether the college or uni class the course as full-time or part time, whether it's funded in whole or part by the Learning and Skills Council, the Welsh Assembly or the Scottish Ministers and the number of guided learning hours.
There's also the fact of whether you will be available for employment if a vacancy or interview arose. You'll see it's not straightforward!!!!
The best thing to do is have a word when you next go to sign on at the Jobcentre.
