C++ placement test online?
I got the c++ certificate at sololearn and I use concepts from (let's say) the first two thirds of the course fairly freely in my own projects. But how do I really get to know what my c++ level is compared to people how actually work with c++ irl. I know that the expirience is really important there but i wanna know what is a 'must' apart from the concepts in this course and also would like to get tested online with some short or long problems/projects, whatever. Do you know any website where something like that could be done for free? (I dont need a real certificate)
