Ive done both A2CofC and GVC courses with Coptrz both almost exclusively from my mobile phone. The videos content is a bit dry and could be improved and the exam process could be an issue for the less techy people out there. I would like to have seen more real world imagery to compliment illustrations. The supplied documentation for checklists and the Ops Manual was excellent making a complex task much easier.   Freddy Dresden handled my flight assessment and deserves a nod. He made me feel very relaxed and clearly knows his stuff. Overall, a top notch bunch of knowledgeable people who are friendly and keen to help.
