Building on what others have said, here’s a tip I learned from my instrument instructor.
When you are filling out CRAFT you can make it easier for yourself by writing down what you can predict they will give you.
For example, the C is obviously going to be where you filed to, so you can fill that out. You will probably also know what route to expect in sim so you can fill that R out too. You can also reasonably guess what departure frequency will be, so that’s F filled out too. All that’s left is the A and the T, which is much less writing to do in the span of several seconds. Of course, listen to the whole thing as they may throw you a curveball on the other letters, but most of the time, pre filling it out as much as you can before getting the clearance helps a lot.
