I am almost done with all the items from Новичок I & II, but when I give a look at other articles in the library, they seem to me much more difficult, with many, many new words.
What are the easiest articles after Новичок’s? What do you advise?
It is largely a matter of what interests you. You should look for items that are not too long, and where the number of unknown words is relatively low, but most of all, items that interest you.
You may find yourself slowing down at first, but I think you are ready to make the jump to authentic content. Good luck and let me know how it goes. You will probably end up saving a lot more LingQs than you have been.
