Oh, wow ! 

There are SO MANY courses available online ! Some are completely free. Some have a so called "free" trial period of 1 week or more, but you have to enter your credit card information! Some are just websites with courses, some have videos, and some are online boot camps. You can pay for some in installments, but can pay for some after you have been hired. Some have great reviews, and some don't. Yes, so many choices can cause confusion, but they can also be good because the competition will lead them to improve and offer more value !
