p.s. In all my life, I've been told hundreds of times to slow down. I've never once been told to speed up. I suppose the only person that feels the need for speed, is the pianist.
Same situation in my case!
Im not sure what tempo marking should be but my book says minim=60 which is generally much slower than the recordings ive herd.
Tempo = 60 for a half note? That is already pretty much, considering that you play only since two years. I could imagine, this is too much. Don't care how fast the best players in the world play that etude. Better take care for playing it well and musically.
In addition to all the tips here I would practise mostly hand separated, and memorize the piece hand separated. This way you listen more closely to every note and eveness in both hands, and, in my experience, you memorize faster at the end.
