I've taken the liberty of cutting the following "Point and Power" technique from a post elsewhere by BEagle, who you may be aware is a high hour pilot on jet and light aircraft and an examiner/instructor too.....
Roll out of final turn at the normal point.
Select full flap, adjust attitude to achieve approach speed, trim to maintain that speed.
NOW TRANSFER YOUR ATTENTION TO THE TOUCHDOWN AREA and choose a specific point on the runway to aim at.
Point an imaginary spot on the windscreen at your chosen aiming point and keep it firmly 'on target' by use of the aircraft primary controls.
Glance at the ASI - if approach speed is correct, leave the power set. If it is low, gently increase power by about 50 rpm;if high, reduce by about 50 rpm. Look back at your aiming point - has it moved? If so, point the ac back at it.
Repeat the cycle 'Touchdown point - speed - power. Touchdown point - speed - power' all the way down the approach until the flare. Then gently close the throttle fully and apply sufficient back pressure to reduce the descent rate to zero, look at the far end of the runway and allow the ac to sink the last 1/2 mm onto the runway....
I hope that this will help you. Getting too low on final is a potentially dangerous situation and you are wuite right to recognise that as a flaw that must be addressed.
Good luck.
