Both 'reassess' and 'reevaluate' are correct and commonly used in English. They are synonyms that mean to assess or evaluate something again. The choice between them depends on personal preference or the specific context in which they are used.

To reassess is to reevaluate. When you reassess a situation, you analyze it again to see if you come to the same conclusion about it. Reassessing is typically done because something about the situation has changed.
