A Script Kiddie’s guide to Passing OSCP on your first attempt.

Sir, i’ve a question. While doing my OSCP, can i use nmap vulner to scan for CVE then access into it’s script. instead of using metasploit to automate. i “kiddie script” manually. in this situtation do i need to cite the source of the script (probably with screenshots or whatever means)? and will i fail the exam?
