Help please please Drawing histograms

I don’t know how to draw frequency histograms.
My professor said the class widths should be equal.
Is the histogram drawn for the data below correct ?

I know it doesn’t make sense to go -ve but shouldn’t the real grade boundaries be used ?

histograms with equal width boxes should have the frequency as the vertical measurement.

for unequal width boxes you need to use the frequency density instead.

it would make more sense if the values were given as

0 ≤ V < 3
3≤ V < 6

etc

Ok so I always do it that way ?
I mean, would 0-2.5
and 2.5-5 not work ?
