You're on the right track to Pass with Jack!
Only noobs use the basic calculator and scratch paper provided by Prometric. But you? You're smart. You're about to complete my quick and free spreadsheet course which will tell you the secrets of how to use the AICPA Spreadsheet!
I'll share with you how it looks, what formulas I recommend remembering, and how to use Excel in general. Don't go sharing this knowledge with your coworkers though, because then you'll be known as the "Excel Guru" and your entire career will consist of "how do I do this in excel?"
Don't be a noob. Take this course. It's free!
