Yes, that's my impression, though it strikes me more as challenging than unreasonable.
Sir, can you check question 33? is that right? Aren't they independent events? So shouldn't it just be calculating the z score of z=(130-100)/(15)?

Q10 is wrong

Q21 has an incorrect turning point

Q22b is slightly flawed but almost correct

Q23 has been differentiated incorrectly and made the assumption that b = e, which is wrong

Q27d is debatable

those r the ones that are wrong as far as I'm concerned but everything else looks 100% all g
bruh then I'm slightly lower then
