Alt-key shortcuts and calculator discipline that save minutes across a sitting.
The real test driver supports keyboard shortcuts, and they are faster than the mouse once trained: Alt+N for Next, Alt+P for Previous, and Alt+F to flag the current question. In Quantitative Reasoning, Alt+C opens the on-screen calculator. A second saved on every navigation is a question earned across a full sitting.
Train them during practice, not on test day — shortcuts only pay when they are reflexes.
The on-screen calculator is basic and slower than you are: it has no order of operations and you drive it with the keypad. Use it for ugly division and multi-digit multiplication; do round-number work in your head with the percentage ladder instead. Reaching for it on every step is one of the most common pace leaks in QR.
Check Num Lock is on, keep one hand on the keypad, and type rather than click.
Before any calculator work, estimate the answer to one significant figure. If the calculator result lands far from the estimate, you have fat-fingered a digit or misread the data — and you catch it immediately rather than gifting away the mark.
