A new way of grading the Leaving Certificate is being introduced this year.
The new grade scheme will see markings like an A1 replaced with H1 (for a higher level paper) or O1 for an ordinary level paper.
An 'A2' or a 'B1' - between 80 or 90% - will be worth the same amount: either a 'H2' or an 'O2'.
It will see several grades done away with and amalgamated, and the new system will no longer use the likes of A1, A2 and so on.
The new scale has eight grades at both higher and ordinary levels - the highest grade is a Grade 1, the lowest grade you can get is a Grade 8.
Grades 1-7 run from a 100% to a 30% mark and Grade 8 will stand for percentage marks between 0 to 29.9% and will stand as a fail.
