Polish Language Course at the Weekend Suggestion

Hi everybody,
I am looking for some online Polish courses to improve my language skills. I did an online course last year in Krakow and really enjoyed it. Now, however, I'm quite busy during the week, so I've been looking for weekend courses, preferrably intensive courses. I have found various offers from different companies, but I am not sure if they're any good. Has anyone done some online courses recently and can recommend any?

The courses I am currently looking at are from Glossa, VARIA, Teach me Polish.
Any advice would be great. :-)

I do lessons with a private tutor via Preply. Can send a referral code and the tutor if interested ;)

Thanks, but I prefer a course. :-)
