Lesson Order Recommendation

Does anyone have a recommendation on how to order the lessons?  I've been following the lessons in numerical order and the transition between the interactive and culture/grammer feels awkward.  Is it better to jump between, i.e 1.1 to 1.5 then 1.2 to 1.6 or is it just better to go through as they are numbered?

You can do the lessons in any way that suits you, but it is probably best not to stray too far from the numerical order  as the grammar is introduced at the appropriate time and things build on knowledge from earlier lessons. There is nothing to stop you jumping on to a topic you think will be particularly useful or even omitting things that that you don't find useful
I just went through everything in order and it worked for me.
