You’ll have to understand that Blender changes a lot and quite frequently. A good portion of the tutorials and documentation that have been written could be outdated, so the interface may look a bit different. But for the most part the old tutorials still apply to the new versions so we read them anyway :).
You could rearanged the panels but you won’t be able to rearrange the buttons themselves. New ones are also added and some might have been removed due to redundancy.
Personally I would just understand where all of the buttons are and then when a tutorial shows pictures of where they used to be you’ll still know where they are.
In the top link in my sig is a link to version 2.25, the one with the interface you see in the older tuts. It’s ideal for learning and you can have it loaded alongside v:2.36. Once you know your way around the transition will be a breeze.
