No matter how good the school, they're still up against the clock. Take advantage of every single day by being there. If worse comes to worse, and only then, be prepared to accept that maybe trucking isn't for you. It truly is not for everyone. It is simply not true.
Most people can learn to operate a truck.
That fact has nothing to do with whether a person actually enjoys driving a truck. Further, don't let yourself believe that passing the CDL tests makes you a truck driver. These tests are very minimal and in all reality, are far too easy. You simply can't afford to take this chance. Don't resist learning things because you don't see the importance of the issue.
