Pprune will give you better answers. For what it's worth, the exams are not translated from Spanish, but they come from a central EASA database and you will find the same questions word for word in the commercial study guides (in English.
As far as Aerolink goes, I have personal experience there and even if the guy on the phone didn't have the best English, they do have some really good ATPL instructor, some who speak great English and even some native English speakers.
In Spain, all ATPL test questions are multiple choice. In Germany, they have many questions that are open answer. Spain now has computerized testing.
