Rz,
Follow RBF's advice.
One point though - 65 kts is a bit fast. I suspect you have been given a Vref for an aircraft at gross weight plus a "flying-school safety factor". It's been a while since I flew a 172, but I suspect at typical training weights, 55-60 kts would be comfortable. I routinely use 60 kts when flying a 182 solo, with half-tanks. Talk to your instructor about it and look in the POH for the actual stalling speeds and multiply by 1.3. The 172N POH I have, only quotes stall speeds for maximum weight (2300 lb), but the minimum full-flap (aft CofG) stall speed is 36 kts (47 kts Vref) and the worst case flaps-up (forward CofG) is 47 kts (61 kts). These speeds will be lower with lower gross-weights.
And another point - I glance at the ASI during the approach, but I don't look at it again, once I've started the flare.
