Yes, but do enough careful broker research to make sure you open it in the same place where you’ll eventually open a real-money one, so that you’re failiar with not only the platform but the broker itself, all their rules and policies, and their support staff. These things all matter, and it would be a mistake to have to deal with them all for the first time when actual money is also suddenly on the line for the first time.
Whether you’re working full-time or not, reading this thread will also probably help you.
Good luck!
