You get a formula sheet, but it doesnt have all formulas. You can check it, its is on the second and third page of each past paper

For Q3 Is the life span of a man really 2x10^9 s??? WHy isn't the answer D?
2x10^9 is 63.3 years
the real average life span of a man is 68.2 years which is 2.15x10^9. Hence it is incorrect by a factor of LESS THAN 100 not MORE THAN 100

Q7 somebody pls!
