I have passed CCSA R80 for seven months，now my company requires a ccse certificate.
but I didn't find CCSE R80 study guide，so I want to take CCSE R77，please tell me can I take CCSE R77？
The R80 CCSA is not a prerequisite for the R77 CCSE. They are on different tracks.
See the course overview as we do not have a Study Guide for the R80 CCSE:
