take two weeks Practice each from them for about 30on to 1 hr each, after two weeks take.stock of the the two you have progressed the least on, set aside for later, of those left practice them about 1 hr each for 2 more weeks, then re evaluate at the end which one you LIKE the most , if you love both equally, choose the one that is least similar to what you've recently learned or played
You've played a lot of etudes lately...what makes you want to play another??
I see. I am a freshman pianist also..Good luck!
