Rara if this is your first time in snow then all i can say is practice. Snow is alot slippier than you may think. Go to a BIG open (light post far apart) parking lot and practice driving (in the snow of course). It may sound funny but do it. Don't get over confident and screw around till you know what you are doing.
From slow speeds in the parking lot try braking, down shifting, and turning. learn how to accelerate on snow. After you get confident on the basics of driving (especially how long it takes to stop) you may want to try skid control. Just take it slow... don't be dumb and bomb into a parking lot at 50mph and pull the handbrake. You'd be surpised how much better of a driver you will be. I have used my skid practice a few times to get out of situations where i would have hit another car or a curb if i didn't know my car. Practice also goes for when you get a new car. All cars act differently.
The one thing that alot of people think is that they can give the car gas (spin the tires) and turn it...I love showing people this doesn't work (i go about 20mph and then gun it spinning the wheels, and then saw the wheel back and forth and the car continues to go in the original direction and doesn't even atempt to turn)
