It has changed from 4 weeks of power point class graduation to almost similar to SFAS physical level. You will do 12 mile ruck <3 hrs. 5 mil run <45 min. That's graduation requirement. BTW be ready to ruck for around 20 miles with ruck (some surprises in engagements) and 3 hours of sleep for 5 days. If someone is on profile don't even try as they don't let you start selection. Let me know if I can answer any specific questions if you have. Its worth doing everything as branch is well recognizing and growing well.
CA Assessment and Selection is different than SFAS - some say harder. Very few make the switch to SF - CA has a higher retention and promotion rate than SF. More have switched from SF to CA than vice versa.
