Welcome Roge, the Bardic course is quite intensive I don’t know if this applies to everyone but I find it difficult to study further outside of Bardism due to how deep this study already is. Music, song, poetry, writing, art, storytelling and performing are all good areas to study, this is generally the sort of thing which Bards ought to be doing. Try to find groups for these if you can as working an audience is a very useful skill to acquire. This should gradually become easier as we move out of lockdown. The Bardic Handbook by Kevan Manwaring might be quite useful, apart from that I am not sure whether there are many specifically Bardic guides available I will attempt to look into this. Also Roge, look at the current guidelines for students on the downloads page as it contains certain advice regarding sharing your work as proof of Bardic learning, either here or elsewhere or with a tutor. This may provide you with a way to measure your improvement, I must use this more myself.
