I have got to lesson 10 (level 2) and I have listened to the first half of the lesson. However I cannot repeat much of it; say less than 10% - my question is; should I just continue to plough on through it?
I get very stuck still trying to say a tiny bit of the last sentence, so much so that I miss the next sentence!
What should I do? This doesn’t feel good 
There could be several different things happening here - you might just need to carry on past it, and revisit it to see if it feels different once you’ve gone 5 or 10 sessions down the road - or you might need to take a few days off and then give it one more shot…
But one thing to be careful about - if your definition of ‘less than 10%’ correct includes all the long phrases where you can’t quite get the end, then give yourself a break - if you’re very mathematical, count any long phrase where you get the first half right as a win!
And, even more importantly - once you lose the race with Catrin (it’s fine for you to talk over her, but once she says the bits you can’t get out) let that phrase go - listen carefully to me (and perhaps shadow what I say - repeat it as a quick little echo) and then have your focus ready for the next English phrase.
No individual phrase is vital - it’s all about the overall pattern - so you’ll be far, far better off taking the hits and getting your focus ready for the next prompt than getting properly stuck on an individual phrase… 
Oh I count anything I get correct as a win 
I have always been happy with half a sentence, I figured the rest comes with time and practice!
When I say less than 10% - I mean of words not just the number of sentences. Right from the start of lesson 10 I went blank and couldn’t recall anything - no words (let alone sentences!). Most I either couldn’t remember, got wrong or at the very best, I said in the wrong tense!
I have never been this bad before, always at least got the verb or tense correct, always something to make me think I’d get it eventually but this is new, I have nothing not even little bits of words/sentences to hang onto…
…maybe I need a break or maybe (I know I shouldn’t say this) I need to go back a few lessons!!!
Apart from the fact that ‘wrong tense’ isn’t something to worry about, that sounds mostly like overload (the brain can decide to have an off-day for plenty of different reasons!).
I’d give yourself a few days, and then have another run at 10 and see how it plays out…
Gave myself a few days off as suggested…
Did challenges 11, 12, 13, 14 & 15 today! Now my head really, really hurts and there are bits I can’t even pronounce yet but I am pushing through them regardless!
After a break it doesn’t seem to matter so much that I can’t remember most of it!
I do wonder what is going on in my head because I get a strange enjoyment now from getting them all wrong and carrying on anyway 
Wow! Now that’s a serious win…
And if you have the rare ability to be relaxed about the stuff that drives most people up the wall, you are very well placed to do some amazing things. 
Keep at it, and keep letting us know how you’re doing, and you’re going to get there - wherever you need ‘there’ to be
Big jump/gap between challenge 9 and 10. Not a gap but a chasm… Only way to build a bridge is to go back…no shame in that I suppose.
Yes 10 seems particularly difficult and because I had just done several other lessons as well, I think it was all just too much for my poor brain to cope with 
I left it alone for a few days and then just carried on but I did notice that because lesson 10 just hadn’t gone in at all - I had big chunks missing for the next few lessons.
It’s interesting that you call it a ‘bridge’ because that really does seem to be how it works. Really struck a chord for me…
It seems that if I struggle with the bits where Aran is actually “teaching” a new bit; then I just can’t seem to recall it at all later on, not even the first letter or a sound; just nothing!
I HAVE to go back, just back to the “teaching” bit and make sure that I can do that section because it starts to affect the later lessons.
It’s almost, as you say, the bridge hasn’t been built and so I have to go the long way round, eventually this is too difficult and I can only cope with one or two missing bridges or it becomes too tiring!
The list of vocabulary for each challenge is very useful for building specific bridges, as I can find which phrases/words I am missing quite easily.
I have to say there are probably only 2 or 3 phrases I have really struggled with getting to go in at all and I’m now at lesson 15 - so I don’t go back very much but it has been necessary a couple of times!
I am also only talking about completely drawing a blank repeatedly over a period of time and not phrases in the wrong tenses etc - so totally no bridge at all!
It is intresting to notice how some phrases my brain just doesn’t seem to like and how some bridges are more difficult to build
It sounds as though you’ve got a very steady approach working well for you there. It would be interesting to see what would happen if you struggled with a new item, and then carried on for several lessons without revisiting the original presentation - I’ve experienced ‘didn’t get it at all’ with new material that has then later on become ‘clear’ because it’s been revisited often enough - the brain clearly can (or perhaps always does) learn words partially, in a gradual process of accretion…
But if you’ve got a set approach of going back occasionally just to the new item, there’s no need to fix what ain’t broken - keep on doing what you’re doing, because it’s clearly working…
Oh I do wait - at least 5 lessons!
Then I really know which things I am totally missing and make sure they are not just things I find difficult to remember.
Like I say it’s only happened 2 or 3 times over both level 1 and up to lesson 15 level 2, so not much…so far 
I have moved on to level 11 with a sort of ’ to heck with it’ kind of attitude. Already enjoying things again!
That’s the magic sauce right there…
