These issues occur mainly in the practice mode, and become clear when using the '3 consecutive right answers', alternative learning mode.

These issues are:

1. In alternative learning mode, the next grade box lights up, even though the question hasn't been answered correctly thrice consecutively, only to return back to the previous grade when the question is asked again.

2. For a new word, that hasn't been learned yet, if the user answers it correctly the first time, ie. he/she knew the word already, the grade should increase from 0 to 2. (0 to 1 for having learnt the word, and 1 to 2 for correctly answering it). This would signify that the user knew the word already. But, even though the practice mode shows this increase in grades through the boxes, it doesn't actually increase the grade twice. The next time this word is seen in practice, it is actually at grade 1. This is actually an effect of issue 3.

3. Parley doesn't increase the grade from 0 to 1 (new to learned) just because it has been seen once, in case the user answered it correctly. The increase seen is actually due to the "answered correctly" part and not the "this word has been learned" part. The effect of this issue can been clearly seen in alternative mode. In case the word is answered once correctly, the next occurrence of the same word doesn't have the grade 1 box lit up. And starting a new session without answering thrice or answering wrong, results in the word being marked as unseen.

PS: These also occur in the normal mode, but it is much clearer in alt. learning mode.

Reproducible: Always

Steps to Reproduce:
1. Go to Configure Practice->Advanced Settings and check 'Require 3 consecutive correct answers'.
2. Start a lesson in practice mode in multiple choice mode (any other than flashcard mode actually). Getting a completely new lesson or removing grades first is recommended.
3. Answer the questions, and notice the grade boxes.
Actual Results:  
1. If the question was unseen before (grade 0), and you answered it correctly, the 2nd grade box lights up even in the 3 consec. mode.
2. When the question appears again (3 consec. answer mode), it again has no boxes lit up. This causes confusion to the user.
3. If you do not answer the word thrice, and don't answer it wrong. (ie say only once and exit practice), and then start the same lesson again, none of the boxes is lit up. (this means it views the word as unseen and not practiced, which obviously isn't true).
4. In case you correctly answered a completely new(unseen) word, ie in the first try in normal mode or thrice consecutively in alt. mode, the 2nd grade box lights up. But when you start the lesson again, only the 1st box is lit up.

Expected Results:  
1. On seeing the question once, (whether it was answered correctly or not, and whether it was in normal mode or alt. mode) the word should always go to grade 1. No exceptions.
2. Now, if the word is accepted as correct (after 3rd consec. answer in alt mode), only then should it increase to grade 2. (this will be seen as jumping grade 1 in normal mode).
3. As a result, on confronting the same word/question again in practice, it should have 2 boxes lit up and not 1, if the above sequence of events did occur. (you already knew the word and answered it correctly)
