IO540 is totally right about Airpseed control and also about landing speed being dependent on different configurations. one of the intergrated schools (Oxford?) teach this from day one. In airliners Vref can vary by as much as 40kias!!
65KIAS is the landing speed at MTOW with flap 20. If you just completed a long XC flight and instructor jumps out and you try to land it at 65KIAS/flap20 you should expect a to float a bit. I'll personally use about 60kias if i'm solo and less than 3/4 fuelled. But its better to use 65kias for now and later on as you get more confident you can experiment with different airspeeds. the PA28 i fly is supposed to be landed at 75 kts at MTOW but on my last flight i was solo with 1/4 fuel and i had no prob landing at 65.
Safe flying
