Say I got 54% for module 1 which is 80% of my total grade and 51% for the second which is the other 20%?

0.54 * 0.8 = 0.432
0.51 * 0.2 = 0.102
0.432 + 0.102 = 0.534 = 53.4%
0.51 * 0.2 = 0.102
0.432 + 0.102 = 0.534 = 53.4%

You take the weights, which should add up to 1 or 100%, and multiply them by the scores, then add the products.
Your total grade is .8(54) + .2(51) = 43.2 + 10.2 = 53.4
Your total grade is .8(54) + .2(51) = 43.2 + 10.2 = 53.4
