There are some flight lessons and ground lessons that, by their nature, should not be rushed or constrained to an hour. These are the foundational lessons, and they take as long as they take.
Do not check the box until you have learned it, and learned it well, and, most importantly, learned it correctly. Failure to do so can come back to bite you in a big way. That could mean failing a stage check or check ride, or having a situation become life threatening, such as missing something during the preflight inspection that results in an aircraft accident.
