I'm glad that you've changed your mind about the checkride
The first time that I had a reasonable gap between flying, I too thought that this won't be a problem at all. I did however have to do a check flight with an instructor (didn't mind doing so, as I thought it would be a formality) I was really surprised at how rusty I had gotten.
The instructor was happy with my flying, but I was really surprised at how much extra mental effort it took me to so that had previously been automatic.
As you get more experienced, you'll find that you can take longer gaps and still be competient, but at your early stages I think you'll surprise yourself at how much skill you have lost in the gap inbetween.
