I have been learning on the old courses of the Welsh course since 2013. I got to about lesson 18 of course 2 and have been using the lessons on the app since then. I have just subscribed to the website and found that there is a new set of courses in place of the old but with the old still available.
Do you think I should try to keep learning on the old course from where I got to or give the new course a try?
