What do you want in a gel system?
Do you want a Hard gel, that is a buff off gel which will be strong for heavy handed clients, or would you prefer a soak off gel system to run alongside your L&P acrylic enhancements?
What kind of course are your local Beauty School running, do you provide your own kit? How would they know the best way to apply a gel if they have never worked with it before, or have several different brands being used in the class.
If I were you I'd do some research before you choose, then do the training provided by the distributor of that system then you will get the best training and ongoing back up.
If anyone wants to recommend a gel system here for the OP, then please say why it is good, there is no point just posting the name of a gel.
