Hello,
If I'm honest then I would say that now may be a little late in the day to arrange an observation. The reason being that an observation period takes time to organise and this point in the year is very busy due to staff change and new recruits.
However, I would recommend writing to the head of physiotherapy for George Elliot and Solihull and ask them very kindly if they can spare the time for you to shadow in their department. They usually offer very good observation sessions, however this is normally around Easter in my experience.
Good luck with your applications,
Dave
