Here's something most prep guides don't tell you: A calculator is permitted during the Cubiks Logiks numerical section. Knowing this changes how you prepare. The focus should be on data interpretation - reading tables, graphs, and charts quickly - not mental math. The calculator handles the arithmetic; your job is to set the calculation up correctly.
And setting it up correctly is exactly where most candidates go wrong. Under time pressure, people read the question, see the numbers, and start calculating, often solving for something adjacent to what was actually asked.
Take two seconds before engaging with any numbers to confirm: What unit is the answer in? What operation is required? Which rows or columns are relevant? That brief pause prevents the most expensive error type in this section.
A faster approach to answer elimination: Rather than calculating every option in full, eliminate obviously wrong answers first, then calculate only between the two or three that remain. This saves time on every single question.
