My laptop takes hours to render

Hello everyone. Wanted to ask about render times on blender. It my first time using blender. I’m doing the blender guru donut tutorial, I’m in part 12 and when I try to render the donut, it says it’s gonna take 10 hours. Is that normal. I wanted to ask because it’s kinda just discouraging me from trying to make my own blender projects, because they might take even longer.

Also if I leave it to render overnight, will blender shutdown or is it ok. I have an intel core i7, so I think that’s why it’s so slow.

Anyways, just wanted to ask is it normal and should I still continue using blender. I’m in university, so there’s no way of upgrading.

Thanks for your help.
