Yes, not when I studied either. We similarly had such courses, but they're brush-up courses, not courses teaching the deep fundamental skills that I believe are needed. It worked fine, but I believe that with real training in doing algebra and calculus mentally can get you further, but that this training takes more time and requires actual tutoring if you want the broad masses of suitable-for-university students to acquire the skills.
