Hi,
I’m currently a third year law student!
You are still at very early stages and so, as suggested by other users, there is not a lot to do!
However, if you do want to get a head start you certainly can.
You could try and boost your CV in various ways such as attending open court and sitting in on cases to see how it all works. There is always a variety of cases and areas of law to watch. You could pick up a law book and have a read. You could ask for some more work experience at law firms or public sectors such as a local Citizens Advice Bureau.
Hope this has helped :-)
