Breaking Through

I finally broke through my 68% wall. I am now taking daily practice tests of 75-100 questions in one sitting (which was hard for me at first) and am in the 70-80% range, depending on the test bank! I'm concerned with my 8 am test time since I've been waking up late and taking my time getting ready in the morning. I also tend not to be a morning person so my next goal is to train myself to wake up and be mentally awake earlier and earlier. My thought this morning of waking up early and taking a practice test resulted in me staying in bed until the usual time of 9am. It's been so cold in my apartment in the mornings that waking up early has been really hard for me. It's OK for me to wake up early and then leave the apartment but if I know I'll be staying at home it's hard to get motivated to actually get going early in the morning. I have to work on this before test day. Any suggestions?
