The score out of 800 allows more fine tuning than the score out of 51 does.
For example, if we express 74/100 and 66/100 as scores out of 10, both would be 7/10.
But the student with 74/100 has done better than the one with 66/100.
Similarly, even if two students have the same quant and verbal scores, their performance level isn't necessarily identical.
The difference will show up in the total score out of 800.
The total score is not calculated using the quant and verbal scores as input variables.
