In a math test, there are 8 true/false questions, each question is worth 5 points, and the total score is 40 points. It is required to mark a check mark ($\surd$) for correct answers and a cross mark ($\times$) for wrong answers. The answers and scores of four students, A, B, C, and D, are shown in the table below. Find the value of $m$.

| Question | Student | 1   | 2   | 3   | 4   | 5   | 6   | 7   | 8   | Score |
|----------|---------|-----|-----|-----|-----|-----|-----|-----|-----|-------|
|          | A       | $\times$ | $\surd$ | $\times$ | $\surd$ | $\times$ | $\times$ | $\surd$ | $\times$ | 30    |
|          | B       | $\times$ | $\times$ | $\surd$ | $\surd$ | $\surd$ | $\times$ | $\times$ | $\surd$ | 25    |
