Have you watched the free lectures and as a result calculated the tick value? The calculation of the tick value already includes the 3/12!
The contract size is $1M, the tick size (as always for interest rate futures) is 0.01. Therefore the value of a 1 tick movement on 1 contract is $1M x 0.01/100 x 3/12 = $25,
There is never any need to use ticks in the exam (unless you want to) – I never do 🙂
