Ok, how about you link to the website of the school and we can all have a look at it?
I'm assuming those numbers are for a C150/152?
How many they have ?
What if there's a problem with availability?
Unfortunately the more unscrupulous schools will overbook a type so students are forced to fly another more expensive type.
Under FAA rules it's also allowed to have airplanes '141' and airplanes not on the '141' certificate as MX requirements are different.
Wouldn't be unusual if they have a couple of 'timebuilders' which are not on the 141 certificate.
Anyway, most of us are here to help so all you need to do is ask
