8/365 DAYS to B2

If you know, I was on univeristy today. I'm very tired, because I slept to short yesterday. Therefore this entry will be very short. I know, I should study all the time, but sometimes it's impossible. When you study something different you have less time to study English. I know, it's any excuse, but sometimes you have few strength. It's a one of words which spelling I have never remembered. Therefore I wrote this in bold. What else about me? I think that good, because I'm starting to recover a good energy. This is already the eighth days to B2. I belive that wonderful!  And today I'm trying to write something different than phrases 'I think that...'
