Hello!
Sure - it's more important to teach how to not get into a spin - but I reckon it's very good practice to rehearse the exit of a spin also.
I disagree. (And with me the writers of most training syllabi of the last 50 years...). You might be able to get your training aeroplane out of a spin during the first year after your course. But thereafter, this ability becomes gradually lost due to lack of training. And what worked fine on your trainig aeroplane might not work so fine on the aeroplane that you will fly once you have your license. Anyway, considering that most spinning accidents occur at very low level - usually at traffic pattern altitude or below - spin recovery practise is not something that is ever going to save anybody.
Greetings, Max
