I need IT help (getting a laptop)?

Ok so I'm going to college and I need a laptop tablet and I'm not really sure about what to get. I've been looking into the Lenovo Yoga, Dell Inspiron etc but have no idea which one is better. I don't really know a lot about IT to begin with just stuff like the higher the ram the faster blah blah

I open to the most 10 tabs but usually only like 3-5
I watch YouTube and movies a lot, blog etc
I want something that's maybe 12-13 in but under that it'll just be like a tablet so no
I'm thinking about waiting till Black Friday because I have about $300 now and will get about $600 or more by then

I have no idea what an Intel core is and which one is better but I just want something that works well, isn't like $1,000 and allows me to use a bunch of tabs without slowing down and taking up too much space

I appreciate all the help and am really grateful.

Plus I'm a student and I don't want something that keeps dying on me, it should have a good battery life
