Do you keep all of your tree gold?
When I first started on Duolingo a few years ago, I would not bother keeping all of the lessons gold. However, this time around I make sure that before I learn anything new, I always strengthen any skills that are not gold. I'm about half way through the tree and on average I have to strengthen about 1.5 lessons per day.
How do you manage your lessons? All gold or not?
I try my best to maintain the strength of my skills; I can't stand seeing one that isn't gold without having the urge to fix it. Besides, the weakened skills show you when it's time to practice, so I take Duo's word and review a skill as soon as I notice that the strength has gone down!
When I first started duolingo I was not interested in it all, but then I realized that you could compete with friends and then I got really into it and I started finishing all the activities and when I see that my trees is not golden I go and do the activities so that the Spanish tree can remain golden and it is an easy way to get XP while trying to keep the Tree golden.
I try to get my (still incomplete) tree back to gold before starting a new lesson. I find that doing those reviews (usually 3-7 nodes/day) helps me fill in the gaps I missed the first time around.
I've got 18 nodes left in the tree as of this afternoon, I"m hoping to have it finished in 3-4 weeks.
I try to, but I don't always manage. Any break of a week or longer will usually result in a colourful tree. With Swedish, Spanish and Dutch I have managed to get them to decay slower, so they now tend to stay gold even after a holiday, but it took me about 1.5 years to get to that point. I followed someone else's suggestion and do at least two general skill strengthens every day (or, since those tend to focus on the early skills, I go through the tree from the bottom up) and after about a year of doing that, a two-week holiday will no longer result in a decayed tree. I have not yet managed to get there in my other languages.
How do you keep your streak going during your vacation? During vacation I do not do any lessons so the strategy I have adopted is to access my browser everyday first thing in the morning and buy a streak freeze to replace the one that was used up the previous day. But once when I did not have internet access, I lost my streak. Is there any way we can buy many streak freezes in advance instead of just one at a time?
