Switching between programming languages

Question

does anyone knows that how I can switch between languages? for example I'm learning Html and I had passed php before, and now I need a tip from php lessons, how can I do it ?

Answer 1

on the app it allows you to look back onto your courses, just click on the course and go to the area your trying to look back on, like if ur in your learning tab, click on the icon of what your learning and it will show you the other courses, and click on the one you want to navigate to.
