The using what you can between times is brilliant, and will make a huge difference.
The triple repetition is a very common pattern, but what is actually happening there is that you are letting your need for conscious control overrule the learning system - your brain is telling you that you don’t know it all, so you’ve got to repeat the lesson. With experience and trust you’ll get to the point where you know that the repetition which builds the learning will come from the way in which we revisit every word and every structure as you keep on going through the course.
This runs counter to most traditional norms of learning, but it’s actually not a bad thing in and of itself.
The problems come from the way in which you respond to this kind of structure - for most people, the month gap (or however much it is) convinces them that they have to start again (from the beginning or near the beginning) - and that of course means they get stuck, and never progress significantly - their own little Sisyphean endeavour…
But if you push on with new material each time you get going again, the first new session will feel painful, but after that you’ll be back up to speed.
Look at the difference.
If you do an hour a day for three days, repeating each session 3 times, and then a month off, and then repeat from near the beginning:
Step 1 - sessions 1 to 2. Month off. Step 2 - sessions 2 to 3. Month off. Step 3 - sessions 3 to 4. Month off. Step 4 - sessions 4 to 5. This is something like your current approach, right?
An hour a day for three days, with no repetition, pushing on with new material after each month off:
Step 1 - sessions 1 to 5. Month off. Step 2 - sessions 6 to 10. Month off. Step 3 - sessions 11 to 15. Month off. Step 4 - sessions 16 to 20.
This second approach will feel much more scary - much more out of control - but it will get you to conversational ability massively faster. We regularly see people who’ve done the 25 sessions of Course 1 (plus the vocabs) getting through a week with no English…
Our record so far for a break, by the way, is 14 months - @louis did 10 sessions of Spanish in a day, then took 14 months off, then revisited the last of those sessions - and said that he got about 40% right straight off, but could sense that he would have been back up to 80/85% if he’d run through it a second time.
So you really don’t need to worry about the breaks…
