Play for a bit to get the fundamentals down. Converts should be fine to play as nothing advanced comes in during 1-2* maps.
But to get yourself started to feel more comfortable, check with your scroll speed and skin. I don't think an offset would matter for now, especially if that has already been fixed during your time in std.
Also, play whichever keymode you want. Find which one is more suited for you.
If you have anymore questions after getting the base understanding of the gamemode, feel free to ask.
