In a C152 Try this.
This is generally applicable to 1000' AAL.
Abeam TDZ (Touch Down Zone) reduce power to 1500-1700 RPM.
Hold the nose until you hit flap speed (white band) and drop 10° of flaps.
Once you hit 70 kts drop the nose a bit to maintain 70 kts. And don't forget the Trim.
When downwind and with the TDZ 45° off your shoulder, turn base.
Now here's the tricky part, The period from just after turning base to about mid-base is where you apply 20° of flap. A hint: if you think you're high, drop them early, if you think you're low, delay it until about midway on base. And don't forget the Trim.
Turn final and honker down the slope, here you will control your ROD with small power adjustments (if needed). Remember that for low Ground Speed (lot's of headwind) you will have to have more power during final than normally.
When you estimate that you could glide in if the engine would quit, apply 30° of flap. And don't forget the Trim.
The most rewarding thing is when you can do this excersise by reducing to about 1500 -1600 Rpm and not touch the throttle until the flare. That forces you to concentrate on when to turn and when to drop the flaps.
Turning on base is the hardest thing to estimate but generally, using the 45° angle to the TDZ works both in still air and in heavy winds.
Hope this helps you with your training.
