Thanks. Wow, so that means I can play the A clarinet. That sounds really cool. I will forget about the bass clarinet.
I did try the google search but I thought maybe the keys might be the same but the notes were different. But I suppose it doesn't make sense for them to make the clarinets all that different.
All clarinets will have the same number of keys and be played in the same way although, as SarahSax said, some bass clarinets will have extensions down to low Eb or even to low C, and as Rosemary said, the spacings are different to reflect the differing sizes of the instruments. If you see a middle C written, cover the same holes whether you're playing an Eb, Bb, A, alto, bass, contrabass or basset horn. The pitch you hear will differ though.

Maybe I should do the Grade 6 Trinity Guildhall because they allow candidates to take the E clarinet or the bass clarinet. It'll look so cool to carry two instruments to the exam hall.
It might look cool, but it'll be a hassle. More instruments = fewer free hands to open doors, carry music and adjust music stands. You also have two instruments to tune.
In any case, the last time I checked, my A and Bb clarinets counted as different instruments
