Hello,

If
Year 1 is worth 25%
Year 2 is worth 75%
Final is then 100%

Thank you

Hi. I concur with dlwilson97.

As you asked for the steps, here's an example of the type of equation you could set up.

Let y represent the score you will need in year 2.

(score in year 1 out of 25%) + (score in year 2 out of 75%) = 70%

(82/100) x 25% + (y/100) x 75% = 70%

Solve this to find y.
