There are sites that offer free training, then you just pay to write your exam. Try www.w3schools.com they have some quality information on programming.

Alternatively you could teach yourself photoshop using youtube tutorials if you are committed enough to actually do it. Try specialize in something with regards to photoshop, like maybe removing blemishes from selfies, or removing backgrounds from pictures. That will be a whole lot easier than trying to learn everything about photoshop.

Remember, nothing comes easy in life and if you aren't willing to put in the hours, you cant expect to reap the rewards.

Good luck
