if you have evedroid, or another type of EVE app that checks SP, mail, etc then you can keep track of all the stuff from in game, out of game… keep in mind, you cannot change what is training, pause, restart etc. all that can only be done in game.
As Pedro mentioned, if you return to the game as an Alpha, you can do limited training, But, if your character is above 5 mil SP, then you cannot train without buying daily injectors or actual injectors, up to 20 Mil SP as an Alpha Pilot.
If you are over 20 Mil SP, then anything considered “Omega Skills” will not be useable to you as an Alpha. Such as flying procurer mining ship, or using a Level 5 of any ship.
