How do I calculate my marks percentage?
Divide the marks you scored by the total marks and multiply by 100. Enter both numbers above and you also get the grade band and how many marks you lost.
How do I work out a percentage increase?
Use the increase or decrease tab. Subtract the old value from the new one, divide by the old value, then multiply by 100. A negative result means a decrease.
