SAT practice clock

It would be very helpful to have a clock within each practice section that displays how long the user has been working on the section. Being that the SAT is a time restricted test, I am sure many people would find it useful to have a clock that starts when then begin a reading practice section so they can manage their time and work toward completeing the practice sections quicker. I am personally studying to retake my SAT and I am working on managing my time in the reading section because I was unable to complete all of the reading section during my first time taking the SAT
