not a hope mate , dont kid yourself , in saying that you can learn enough to get you going in a week , get as many videos mainly on making a selection , layers and masking and adjustments , start with a video of the basics though it will get you started , ive been using it for around three weeks and im on my way( but a lot to learn still ) im more comfortable around my tools , in saying that i have watched a lot of videos and i mean a lot , tip when you look at a video rename it to what makes sense for you EG removing a backround ( this might just be a sub video of folder called selections) , i then put the videos that are really helpful like the removing a backround and copy them to a folder named good tips , this way when you want to remove a backround and are struggling you can replay the video easily if your stuck.
