Some, but it is no substitute for real, or even simulated, trading. Simulated trading can be done with some brokers -- you enter orders just like you would in "real life" except with play money, not real money.
But there is a big psychological jump from paper or simulated trading to real trading. Real trading involves real money. So you may have a good paper or simulated trading record, but when it comes time to pull the trigger in real life -- entering, and especially exiting, positions -- that's when it gets dicey for a lot of traders.
One recommendation is to start out with the minimum reasonable transaction possible. If you win five in a row, you can up the ante. If you lose five in a row, you have to go back to the previous level. Hopefully, you will be able to "ratchet" up to important levels.
