Hi @roel-1
Well level 3 - or the deep end is the structured version I think - carries on the learning journey in the style you are familiar with…
I found the Advanced Content a bit of a up-elavator ie hugely beneficial, in terms of both listening skills (and the need for a bit of heads-down work to make it work)…
…are you in a group to have practice with regular ‘normal’ conversation? If not, the lock down actually has an upside in a sense that there are quite a few virtual meetings going on now.
You can join the Leeds zoom meeting if you are interested - the geographic region is completely irrelevant really - weekly on Saturdays at noon (as can anyone else for that matter - just let me know ) - we have a full range of skills from ‘just started’ to first language speakers.
Starting reading books written in the spoken form is good for consolidation of the grammar you’ve learned via SSIW and broadening your vocab…
Once your OK with that, reading the Cymru Fyw website using the vocab button - gives you a sneaky transcription/ translation of the Radio Cymru news programmes…and then you are cooking on gas 
Apart from that, I can’t think of anything,
