Dreams about exams often reflect feelings of anxiety, pressure, and self-evaluation. In your dream, performing well initially but then being interrupted by your mom suggests a struggle between personal responsibilities and external expectations. This could signify that you may feel torn between your own goals and the demands or needs of others in your life.

The shift from doing well to receiving an unexpected result (intermediate level) may symbolize fear of not meeting your own or others' expectations. Crying in the dream indicates a release of built-up stress or disappointment, which is common when facing significant life challenges or transitions, such as exams.

The fact that you were told you still achieved credits, even if it doesn’t align with your real-life situation, might suggest that you need to recognize your efforts and achievements, even if they don't meet your original expectations. This part of the dream could be a reminder that progress can come in different forms, and it's important to acknowledge your accomplishments, no matter how small they may seem.

Overall, this dream likely reflects your current feelings about exams and the pressures associated with them. It may be helpful to take some time to reflect on how you manage stress and expectations in your waking life and consider ways to balance your own ambitions with the needs of those around you.
