Dreams about exams often reflect our feelings of pressure, expectations, and self-evaluation. In your dream, doing well initially with advanced formulae indicates a sense of competence and confidence in your abilities. However, being called away by your mother suggests a conflict between your responsibilities or obligations to others and your personal goals.

The shift to being told you achieved an intermediate level may symbolize your fears or anxieties about not meeting the high standards you set for yourself or those set by others. Crying in the dream could represent feelings of disappointment or inadequacy, especially since the outcome does not align with your efforts.

The mention of achieving credits despite not passing the course could reflect a desire for validation or recognition, even if the circumstances aren't ideal. It might suggest that while you are striving for excellence, there is also an acknowledgment of the effort you put in and the partial successes you achieve.

Overall, this dream may be urging you to balance your ambitions with self-compassion and to recognize that not every effort will yield the perfect outcome. It can be helpful to remind yourself that exams are just one measure of your abilities and that growth comes from both successes and setbacks. Consider reflecting on your feelings surrounding your recent real-life exam and how they may connect to the themes of your dream.
