I went over things I’d used before; I was able to understand points that had seemed unclear to me; I learnt new things; and I was even able to compare what I saw during the training with what I do at work. A very interesting training course; the content seems quite comprehensive to me, there’s a lot of detail and practical examples; the trainer has a good grasp of the subject and conveyed his knowledge to us clearly and simply.
