I don't think there are really easy marks - but if you remember to always mention tax, reinsurance, regulation and such like you can add some marks to a question that would otherwise have been a disaster!
Like Lin says, there aren't too many easy marks going. Plus what's easy for one won't be easy to everyone. But if you know your definitions and can get them down verbatim I reckon that's easy (and quick). They used to creep into general insurance papers quite a bit (annoying when your memory isn't that great). Not that sure on CA1 but the glossary may be worth a browse (or 2). There are definition qns in the assignments so you never know your luck!
