Akano,
The one-minute break is between sections. Once the time begins for the next section, it will count down, regardless of what screen you are on.
The best practice would be to be completely familiar with the instructions, question types, and answer choices ahead of taking the exam. For instance, in Math, knowing all four answer choices for Quantitative Comparison (i.e. A = A is bigger; B = B is bigger; C = Both values are the same; D = No relationship can be established). That way, you spend little to no time on the exam itself.
I hope this helps,
- Steve
