What are University Rankings?

So you want to study for a degree. Which university you choose will play a
critical role in how your next few years look like and eventually determine
your career opportunities. So you better make the right decision!                                                                                                           

This is where university rankings come into play. 
You need to find the Best Place to Study!                                                                                                    

Keep your budget in mind, figure out your desired location, and so on; but 
don't forget, the academic level and reputation of the institution you eventually 
pick will make a huge difference on the outcome of your studies. University
Rankings are a way to measure these important things.                                                                                                                                   

College and University Rankings are lists of institutions of higher education,
the order of which is determined by a combination of factors. These factors
vary greatly; some of the rankings are based on parameters measuring the
purely academic quality of an institution (citations of the institution's faculty
members, for instance), while other address factors such as the opinions of
your future employers or the mean annual salary of a graduate.                                                                                                                                                                                     

Remember: some rankings are more relevant to you than others!
