Thanks Marios, sorry had notifications silenced so did not see your reply. Good you are hyped about it, software quality is an important thing, an invaluable skill to have. For the exam, study the book and possibly the video course. I made a mini guide on my blog (bobcodes.it) using the guidelines with my code, maybe that’s useful. You need some basics in Java or C# because that is the language used. Feel free to reach out to me for more specific questions.
