soon to have sudo

I'm going through a lab consultant training class and we will be given sudo powers next week for the labs we will be working in. During the class, we will be running around each others computers(remotely), pkilling or just plain killing the processes of the classmate on the computer. So imagine a lab of script kiddies playing with sudo. We are not allowed to script any commands, programs because of the harm they could cause, much less, come on.....my question is: What can I do to prevent people from pkilling me. We have Solaris 5.8. Any help would be much appreciated.....
