A doctor practises (verb) in his practice (noun). Note: In American English, a doctor can practice (verb) in his practice (noun).  In English, the former 'practice' would be a mistake."

correct[12] = "I am off to guitar practice#Practice with a 'c' is the noun, but practise with an 's' is the verb. Remember, practice can often be substituted for training or preparation. This is because they are both nouns too.  I am off to guitar practice/training."

correct[22] = "...I've been practising this trick for months#Practise with an 's' is the verb. It can often be substituted for the verb prepare (in its various forms).  In this example, you could equally say 'preparing this trick for months'.  However, if you find yourself trying to use preparation (which is a noun), then you probably want practice (the noun) as opposed to practise. In American English, practice is both noun and verb, but some observe the rulings with 'c' and 's'."

In this example, you could equally say 'is well prepared'. In American English, although some observe the 'c' and 's' ruling, practice can be both noun and verb. "
