>>12122779Certainly not my case, but it really depends on what your criteria for "low rank school" and "high ranked school" is. If you're taking the university rankings literally, you're not getting much information - in the QS Ranking, for example, Harvard is ranked 3rd in the world, while the Polytechnique is ranked 61st. Yet we both know that a Polytechnique graduate, or any Grande École graduate, in fact, would have no trouble getting a Master's degree from Harvard. Uni rankings aren't really a good metric.
On the other hand, education quality can obviously differ from school to school, and I would recommend you to try to find some your new uni's undergraduate exams and compare them to the exams you did in your old uni. However, I must remind you that if you got admitted in the first place, you're probably not retarded. And even more - Master's programmes are (usually) taught programmes. And unlike with undergrads, most schools give a shit about their postgraduate students. If you go through the programme as intended, and put some effort into compensating for any deficiencies in knowledge you might have, you'll be fine.
