Today I turned off Fixed Root option, which noticeably decreased my success rate. I managed to answer correctly 78/100 questions. I noticed decrease in will to practice as it is work day. Also, I turned off the automatic question forwarding option, so I can repeat interval and remeber its correct name.
Today I started lesson subjected to g letter. I had hard time getting used to writing 3 different letters with one finger, so I went back to the last exercise of the previous lesson. After completing it, I forwarded "back" to the g, but it hadn't got any easier. I do not want to lose will to practice too quickly, so I'm done for today.
