Time out to study

Hi. I am having trouble with LOA4 as I just sort of bluffed my way through the earlier lessons and did what was needed to get the grade so far.  By that, I mean I did what was required for the LOA grade, but it wasn't  based on solid ground with genuine understanding and muscle memory that really sank in and stayed.  I am busy with work and unable to do regular practice so I just can't get past the difficult passages in the test pieces (LOA4 is hard!).    I have the music taped on the wall at work and nibble at a few passages when I pass it waiting for the kettle to boil during a tea break, so I haven't given up but I am really stuck on some bits that will be overcome eventually, I hope.  I was wondering would it be o.k. to unsubscribe for a while, while I keep nibbling away at it and then come back when I feel I actually can do it some credit.  Will all my settings still be there?

Thanks.
