Reaching 300 hours without rewatching?

Hello,

Is it at all possible to reach 100 hours or 300 hours (based on DS roadmap) without rewatching superbeginner/beginner videos? Vidioma only has 50hrs of new starter videos and 144hrs of beginner videos. Is there a lot more CI findable on Youtube that is not (yet) on Vidioma?

Thank you!
