Hi both, thanks ever so much for the great work you guys are doing on sharing your passion - I've started the foundation course with Gem- A in Birmingham Uk and have been listening to your podcasts since inception - it truly is helping me understanding conceptual subjects related to my study which still slightly blurred in my mind so please do keep up the good work and if possible do share us more insights on your learning processes and how did you manage to progress during the course etc which part (s) did you find more difficult and how you've overcome challenging times. With best wishes Mohamed
