What is a "Survey-cum-Tutorial"?
Cum means combined with.  It is a Latin word, but used in English occasionally.  In addition to knowing this definition, I think if you look at the specific example (if there is one in front of you), you should be able to tell what the writer of the phrase meant.  I don't think there is some general meaning (like it is a common phrase) beyond that, so you need to look at the context to see the writer's meaning.
