This isn’t a very long list - but as beginners it’s what we need for now! I hope this is helpful!
60 lessons also - wow that’s a lot, it’s not even been a month! I hope you all are enjoying these lessons.
As always, I’m not a tutor, teacher, fluent or native speaker. I learn on my own and post these lessons to help others learn.
Thanks guys!
