Is a temporary table a good solution for importing temporary data into a database

Question

i am facing the following scenario. I have a student database in which exam results are stored. Every now and then i get a list with the names of certain students for which i need to find out how well they performed in an exam. After i have finished with my queries i don't need the temporary student data anymore. I am trying to think of an elegant way of how to store this temporary student data in my database. The only thing i found out that in my opinion could be a solution to my problem is a temporary table, however i am not sure. My tables have the following structure.

Student
id(PK), matriculation_number, first_name, last_name, course_of_study, email

Exam
id(PK), student_id(FK), grade

Temporary student list
matriculation_number, first_name, last_name

All in all what i am trying to achieve here is import the temporary student list into a table, then compare it with the student table, using the matriculation number, in order to get the id of the student and finally use the student id to access all the exam results for that particular student.

What do you think is a temporary table a good solution for the above problem? If not how would you go about it?

I am using MySQL as RDBMS.
