Hi, when Duolingo wasn't available in turkish yet, I joined a turkish course and we had a turkish course book and in it, the present tense would be described as "root word"+yor+personal ending; but here on Duolingo it's just rootword+personal ending - so i'm confused now! From what I've noticed, the "yor" signals present continuous? I just find it weird that the entire book has something essential like this wrong then?
Your course book is wrong.
"Root-iyor-personal ending" is present continuous.
"Root-a vowel-R-personal ending" is the jack of all trades, master of none. It's a bit like the English present simple, but not really; at times the future tense, but not really; and very often used in conditionals, but it's not the only tense used there, either. It's called the Aorist tense.
