What can be inferred about the tutor's remarks on extra lectures?

The remark that students may choose to attend or not suggests a level of flexibility regarding the extra lectures. This indicates that attendance is not mandated, allowing students the autonomy to decide if they want to participate based on their individual circumstances or needs. The phrasing implies that while the extra lectures are available as a resource, they are not compulsory, which can help students who might have other commitments or who feel confident in their grasp of the material. This perspective fosters a supportive learning environment where students can take ownership of their education.
