Maybe you can find the old videos in the physics archive. I was also doing the HS Physics course when it was deprecated so I used the physics archive.

BSpaceX   interestingly, in the physics archive start page it says, The physics archive contains legacy physics content, and is not being updated with new content. Exercises and mastery mechanics will soon be removed from the physics archive. For our most up-to-date, mastery-enabled courses, check out High School Physics and AP Physics! (I copy pasted).  That's why I am worrying if those videos will be permanently deleted. Honestly, the older videos had much more in depth discussions and had more ways to sort out a problem. The older course also had more topics. So I was wondering if that course could be made available for us international students. If you have any suggestion, please share with me. Also, here's a link to the deprecated High School Physics course  https://www.khanacademy.org/science/high-school-physics

Hi, you guys seem to speak very highly of the old high school physics course. I am halfway done the old ngss high school physics. do you think its worth it to switch over to the other one. thanks

Definitely not, at least in my opinion, the older high school physics course had better content and explained the concepts a lot better than the newer one. In your case, especially since you're already half-way through the old NGSS Course, I would highly suggest to continue that same course. There's a chance that the old courses might be deleted so you should probably finish it while we still can.

Thanks
