Group one words, which end with 'a' are usually feminine. Group two words, ending with 'us' are usually masculine, although can be neuter. In group 3, it can be any, but the neuter ones end with 'a' if plural. Not the best help, but what I know!
I don't know if this is still active, but I study Latin (unfortunately) and might be able to help.
