Did you earn any sort of revenue when it was active?
YouTube recently changed alot of the requirements for partnerships, you need 1,000 subscribers and 4,000 hours total watch time to even just apply for monetisation. If you are not too bothered about this then starting a new channel wouldn't be bad, it really depends on how old the 10k channel is, because most likely they are inactive now so it would be similar to having 0 subs.
Starting again would be difficult, there are thousands, probably even hundreds of thousands of channels similar to lifestyle now, so it's extremely unlikely that you will grow as fast considering how popular it is. However you could offer something unique, maybe like your revision tips? I can't really suggest anything on a channel like this because mine is just programming and hacking lol.
Good luck with it anyway.
