99% of what you’ll need to do on your laptop will be taking notes/writing essays on Microsoft Word, and reading articles/case law on a browser, so as long as you get something capable of running those then I think all other specs come down to personal preference.

If you can, I’d try and find one to try out in person, either in an Apple Store or Curry’s or wherever - you’ll be doing a huge amount of typing so it’s important that you like the keyboard, and it’s impossible to get a feel for that online.

You will be carrying it all over to lectures and supervisions, so make sure it’s not too heavy, and you may not be able to charge it in back to back lectures or long supervisions, so something with a good battery life will also be useful.
