Which pl/sql courses to choose in St. Petersburg?

Question

Oracle

I am self-taught, I started from here sql-ex.ru . I read Oracle PL/SQL for professionals Feuershtein S., Pribyl B.. At work, I was offered to take courses. I started looking and I don't know what to look for. They won’t pay dear ones, but I don’t want to waste time for a piece of paper-certificate.

Answer 1

If Feuerstein comes in normally (you yourself understand what he writes about, and you don’t need a person who would chew it all up), then you will only lose time in the courses. Given the fact that you do not need a "paper".
