It is important ?

CAS helps the students on the development of the personal skills, and the method that is used to reach this objective is the EXPIRENCE.

Also CAS gives the oportunity of colaborate and help with other persons.

At the same time CAS have the important function of give to the student a "relax" of the academy pressure that IB programe has.

But be carefull CAS is not only a moment for have fun or just breath some fresh air, CAS have an important place with TOK and the extended essay. Remember that if you fail any of those 3 courses you can´t reach and obtain the diploma.

In consecuence of that, enjoy CAS but with responsability :D. 

Me at my first expirience (WAS AMAZING)
