The video tutorial reviews an advanced exam paper, focusing on statistics, differential calculus, and integral calculus. The instructor explains the approach of tackling questions by topic rather than sequentially. A detailed walkthrough of a statistics question involving a stem and leaf plot is provided, including calculating the sample standard deviation using a calculator. The tutorial emphasizes understanding the process and checking calculations for accuracy.

What is the approach taken by the teacher to review the exam paper?

• Random order

• Sequential order from start to finish

• By topic order

• Only difficult questions

What is the range of the data set in the first statistics question?

• 35

• 43

• 50

• 77

How is the unknown value 'x' in the data set determined?

• By looking at the plot

• Through algebraic manipulation

• By guessing

• Using a calculator
