No, that's definitely not normal, what i'd suggest you do if you're talking about CS 1.6 is practice bursting (shooting a couple successive bullets) in a fy_snow server or aim_ak-colt server, aim_map is a good place to polish up too, then just play around in dust2 or something, find a team and get a couple of scrims in. Finding a nice team is the best way to practice though I think.
