At my school, we were told that the asessment had changed, and that the 150 hours weren't as important as fulfilling the 8 objectives. Also, that it would depend on our CAS Diaries, and how well were they written, that they would assess us, and judge whether we has achieved or not those objectives. A friend of mine (who is also taking IB with me) told me that CAS activities wouldn't count as extra-curricular at universities, because there are school activies (Festivals, sports competitions) which count as CAS activities. I wasn't very convinced, though, because activities such as school newspaper or forums organized by other schools, are done with permission and during class hours outside.
