it is difficult to explain how bad the corruption is/was. For instance you may pass an exam in university for 20-50$, depending on your major and the eliteness of the university. You may even skip the full educational process and just get the diploma. It is not so easy, but possible.

A driving license costs 200$.

But, there is a decent progress from early 2000s, people get changed and governments get changed/evolve, so in general it gets much better from year to year. Especially when Ukraine changed direction to the West and became pro-European.
