in virginia, are demerit points to a driving record +points or -points?

[Axle]

I got tagged for speeding and I checked my driving record and it says I have "X", i don't remember anything i've done in several years, but my short term memory stinks. the DMV only says you merit good driver points for not getting a ticket every year and demerits for each offense. I've been around too many systems that give + for being bad, and Minus for being bad. Just need some clarification
