Requirements
Delegates attending this course should have some previous programming experience and be able to define general programming concepts including: compilation, execution, variables, arrays, sequence, selection, iteration, functions, objects, and classes. Moreover delegates should be able to navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.

Course Reviews
Brian was the perfect instructor. He was clear and gave great examples as we worked through the content. He allowed us several opportunities to raise questions. The pace of the course was great. I would highly recommend this course for gaining a basic understanding of Ruby and Rails. I can't recommend Brian enough.
Alex - Senior Software Engineer - Government - March 2023
Brian was very knowledgeable and made the subject interesting and relevant to what I needed to know for my work in this area. Very enjoyable.
Paul - IT
The instructor did very well in answering questions. Although I've been using Ruby for 7 years, I still took new things away from this course.
Thomas - SDET - Government
Thanks very much to the trainer. A brilliant lecturer, a pleasure to be part of the class.
Rhys - HEO
Tony is clearly enthusiastic about the subject matter, and this comes through during the teaching, which is excellent and especially important in the current environment we're in. Very relaxed style of teaching that allows for a large amount of information to be given and digested easily without feeling overwhelming Overall excellent, very well taught course
Samuel - Software Engineer
The course was excellent and paced well. As a student who is completely new to ruby and rails my only request would be a more gradual approach to the rails section similar to what was done during the ruby section.
