I want to be a Graphic Designer, but I am currently in the "How To Build A Website" course. Am I on the right track? :)

Hi Aiken, I first misread your question that you wanted to be a web designer, not a graphic designer (oops). As a 4th year graphic design student, I would suggest you start by learning the theory behind design such as the principles of design, color theory and typography. These are the building blocks of design and what differentiate good design from bad design. I would perhaps start with aesthetic foundations and then onto design foundations. Here is a brief explanation of principles and elements to get you going: http://www.j6design.com.au/6-principles-of-design/

Of course you would also need to know how to use software such as Illustrator and Photoshop which there are courses on both applications on Treehouse.

Advancing on from this you need to ask what is it you want to do next? Branding? User Interface Design? Product Design? All of the above? There are some courses here that can help with this such as Logo Design Basics and Usability Foundations.

On a side note I would also suggest looking at semiotics (the theory behind signs and symbols). Here is an awesome resource for begginners: http://visual-memory.co.uk/daniel/Documents/S4B/ .This is only if you really want to get into the psychology behind graphic design but I found it an awesome thing to learn about!

As awesome as Treehouse is, I would not rely solely on it for my graphic design education as in my opinion it does focus more on development. In addition to Treehouse, look at sites such as Tuts+, Skillshare and Youtube for more material. Also as you progress, find some designs that you like and try and replicate them and add your own flair to them, this will help you learn and also develop your own unique style. I'm always looking at sites such as Pintrest, Behance, Dribbble and Designspiration for inspiration :)
