Possibly a bit late but hopefully as a bit of encouragement to the OP I felt I was in a similar situation at the end of last week - I'd got the first part of the circuit OK, and my approaches were in general reasonable (not totally consistent but the bad ones were becoming rarer and rarer), but I just couldn't seem to master the flare and hold off - I'd either do it far too early and have to go around, or do it at the right time but still have power on and thus balloon and go around, or do it late and bounce and go around, and this didn't seem to be improving from lesson to lesson making me wonder if I'd ever get it.
However, this week it was all change - I had a lesson on Thursday where out of the blue I managed 3 perfectly safe landings in a row, with the instructor not having to do anything so clearly something had just clicked. I had another lesson on Friday where I was able to repeat it, and it then came as rather a surprise to me when the instructor then sent me on my first solo, so in two lessons I went from wondering if I'd ever get it and thoughts of giving up starting to stir to going solo and still having a grin on my face now!
