Background

Suanxie is an OIER at Lianhuo Middle School.

As an OIER, Suanxie naturally needs to learn some knowledge that ordinary students only encounter in university, specifically in mathematics. Learning this is not easy, but fortunately, Suanxie met a teacher who guided her carefully. With the teacher's help, Suanxie quickly mastered a large number of skills, including but not limited to calculating the determinant of a $3 \times 4$ matrix, summing divergent sequences and dividing the result by $2$, and inventing a special Chinese notation for derivative symbols... In short, through her hard work, Suanxie became a super-strong expert.

The super-strong Suanxie naturally wants to participate in super-strong competitions. Over the past few months, Suanxie has been focusing on preparing for THUPC—an international competition consisting of a preliminary round and a final round. Contestants who achieve good results in the preliminary round can not only enter the final round and receive stylish clothing, but may also win small prizes and even be interviewed on television. In order to make a splash in the preliminary round, Suanxie worked tirelessly copying her teacher's notes, and naturally forgot about the upcoming monthly exam. Although Suanxie is super-strong in mathematics, the math involved in the monthly exam is different from her usual field, and having forgotten to review, Suanxie could only answer randomly in the exam hall.

Shortly after, the monthly exam results were released, and as expected, Suanxie did not do well. Due to the emotional blow of the exam failure, Suanxie forgot her exact score, but her strong mathematical ability allowed her to quickly recall some other relevant information: specifically, Suanxie's monthly math exam score is an integer between $0$ and $150$, the remainder when divided by $3$ is $2$, the remainder when divided by $5$ is $3$, and the remainder when divided by $7$ is $6$.

Suanxie cannot determine her monthly math exam score based on the information above. Can you help her?
