Hi Ilan iicelp ,
I don't know what you mean exactly, but I would highly recommend downloading Blender 2.64 and use that for this Course.
Once you are really familiar with Blender, the versions used don't matter much anymore. The modeling techniques taught are 'timeless'.
If you decide to stick with 3.6, you'll end up with a lot of questions, the UI has changed completely and a lot of shortcuts are different and some Addons don't work anymore. We will answer them as good as we can, but you will need to be very precise in asking; also add a timestamp.
And please try and use longer sentences, especially if you don't know English very well; nobody cares about language mistakes, but bad English and using only a few words makes it very hard to understand.
Hello ilan. Yes try to expand on the context of your inquiry, it's a bit hard to know what the problem is with so little detail. Also if you haven't watched the Fundamentals yet, you can start with the most basics of courses, that way when you watch a tutorial is easier to follow. A couple of links:
