About this blog

I’m a post-graduate student in technical studies. Math is my hobby. I know from my own experience, that the best way to prepare for math contests or Graduate Record Exam (GRE) is to solve the previous years’ problems.

So, I publish here GRE math problems. The solution of the previous one, accompanied by some tips and strategies, is published together with the new problem.

From time to time I'll post also analytical questions. Athough analytical problems are obsolete in GRE, nevertheless it is fun solving them.
