Another thing that you must consider when it comes to the linux courses is the price. There are different options that you can think about like the Administrator 1 class that costs $4,280, while the 2nd level would cost $4,708 with the exam and $4,280 without the exam. The 3rd level for enterprise administration is $3,745, but with the RHCE and RHCSA is $4,494.
If you are looking for a quicker course you can also take the rapid class option that is $4,494 and only takes 4 days. Pick the one that fits your needs and what you are looking for.
