Unlike the TOEFL and IELTS exams which are only valid for 2 years, the Cambridge exams (FCE & CAE) are valid FOR LIFE! Never take another English exam again!

Does Cambridge Proficiency expire?

Your Cambridge English exam result/certificate does not have an expiry date*. It shows that on a particular date you demonstrated language skills at a specified level, however, language skills are known to diminish over time if not used and maintained.

Is the CAE exam difficult?

CAE is not easy. If you're not actually advanced level yet, it would be pretty hard to pass it. Tasks like word formation or multiple cloze become much easier if you practice doing them, you just need to get a hang of it. And if you find CAE hard after all of this, you might want to study past papers.
