I'īve got the Oxford DVD because it came when I received my books, Itīs a good complement to your study, but it wonīt give you explanations or anything, itīs just simple right or wrong multiple answer questions. As I said itīs just good to either avoid doing always the same questions or complement your study, It shouldnīt be used as a study base instead of a book or the Question Bank. Hope I helped, any questions just PM me
