I'm trying to translate the following into French, and I am definitely stuck: "I have received substantial training in [subject]" My problem is, yet again, with "training"; here is my go at the moment: "J'ai reçu une éducation/formation/enseignement/?? considérable sur [sujet]" Context: it is for a job application. The subject I am saying I received substantial training on, is not the main subject of my studies (I wasn't officially studying that subject), however within the context of my studies, I also received lots of training on it as well - so I am not sure how fitting "éducation" would be here. Oh, I am equally unsure about everything else in this sentence as well, don't get me wrong; I am badly stuck! If anyone could help, I'd be grateful.
