Looking at the curriculum and loads of previous parts skipped

Hi everyone, now I am on the basic javascript section - and I was just marvelling at all my previous completed tasks and noticed there are loads of challenges not ticked! Have they either added new stuff after I completed those sections? Or did the system just automatically decide to skip loads of challenges? I mean as you complete the programme you are automatically taken to the next question, so its not like I skipped them by choice.

Any idea what has happened here? I will of course have to reverse and go back and do them all.

Thanks,
Russell

They added a TON of new stuff. Some is in its own sections, but there are also lessons added to existing sections, so it’s normal to see a scattering of un-checked lessons. It’s entirely up to you if you want to go back and do those or not.
