A very common question I get is: do you need a degree to become a professional web designer or programmer?
Short answer: no.
.. But there are a few things to consider.
Big Companies will want a diploma – for now.
If you plan on working for a big company or government, you will probably need some sort of degree to get in. The exception is if you have a lot of experience in the field. I am guessing since you are reading this, that you don’t.
