Here’s what I’ve tried, from most words per day to least:
Level 1 - Hardcore: In January 2015, Memrise had a contest for who could learn the most new words. I aimed to plant 300+ new words per day. Most of them were Spanish; a few of them were German. At the time, I knew no German, but could already speak Spanish at an intermediate-to-advanced level. Learning new Spanish words was much easier than learning new German words. Working on courses that conjugated irregular Spanish verbs was easiest.
Strategy: Do Memrise until tired, take a 25-minute nap. Do more Memrise. Or do Memrise until tired, take a break and eat, walk, or something, and then do more Memrise.
Pros: By Memrise’s count, I learned over 9,600 words, though as I said above, many of those were verb conjugations. Even if you exclude the conjugations, I learned a lot of new vocab… more than I would have without the challenge. It definitely helped my ability to converse about a variety of topics in Spanish.
Cons: Because I was trying to plant as many words as fast as possible, I didn’t create nearly as many mems as I should have, so some of those words were not as easy to recall as I would have hoped.
Level 2 - Intense: January 2015 was a revelation. Until I tried it, I had no idea I could learn so much day after day. After taking it easy for a couple weeks, I set a bunch of course goals. For about 6 weeks, I learned 150-200 words per day. This time, I slowed down, created mems as I needed them, and got started on German. If I remember correctly, I aimed for 15-45 new German words per day, and the rest was Spanish.
Strategy: Take breaks between learning Spanish and learning German. Create mems.
Pros: I made a lot of progress in Spanish & German, and I earned a lot of points. (I was also reviewing all those words from the January Memathon at the time…)
Cons: I spent a lot of time sitting in front of my laptop! I believe I spent 3-4 hours per day on Memrise. As I worked farther into advanced Spanish courses, I had to create a lot more mems. (Fewer people had learned those words before me, so many of them simply had no mems.) Eventually, I needed a break.
Level 3 - Reasonable: At the beginning of April 2015, I took a few days off, and then went back to Memrise, this time at a more reasonable pace. From April 2015 to April 2016, most months I averaged 50-75 new words and earned 100,000+ points per day.
For the months where I did less, there were good reasons. In August, I was busy with summer traveling. In October, I took a German class every morning for 3 ½ hours. In November, I did a lot of Memrise, but most of it was reviewing, not learning. In December, I was busy with holiday traveling, but still managed to average 25-30 new words per day.
What I’m really saying is that for me, learning 50-75 words per day is sustainable for a long time.
Strategy: Spend 1-2 hours per day on Memrise, split between 2-3 sessions. For example, plant in the morning and water in the afternoon and/or evening. Nap, walk, eat, and/or drink water when my brain gets tired. In mid-May, after I’d made progress learning German, I started learning Turkish and mostly stopped learning new Spanish.
Pros: I was able to keep up this learning pace for months at a time. I learned to read and speak German, and I made progress learning Turkish. (Note: I used language-learning resources besides Memrise…)
Cons: Learning at this level is still a big commitment, and sometimes there just aren’t enough hours in the day to fit it all in… From time to time, I wondered if spending so much time with Memrise was keeping me from using other language-learning resources as much as I needed to.
Level 4 - Consistent: No matter how busy or tired I am, I aim to do something every day. Since May 2016, I’ve been keeping the learning streaks on 3-8 courses. Sometimes I do that with learning, and sometimes with reviewing. I believe I’ve been averaging around 15 new words per day.
Strategy: Do something every day.
Pros: A few minutes per day is enough to convince my brain that Spanish, German, and Turkish are worth remembering. I’m able to maintain the learning streaks in a few courses, as well as my overall learning streak. I’m spending more time with other language-learning websites, including Clozemaster, which I discovered in June.
Cons: Compared to learning 50 words per day, the progress is slow. I’m way behind on watering—the number of words due for review is five digits long. Yikes!
