When filling in a resume or application form, you can fill in the following format: highest education: undergraduate (or bachelor's degree); Graduation time: it is expected to graduate in XX month, XXXX (or fill in the admission time so far).
It should be noted that if undergraduate students take the national postgraduate entrance examination (referred to as postgraduate entrance examination) recognized by the state and are admitted to the graduate school, they can fill in "graduate students are studying" or "graduate candidates", indicating that they are studying for a master's degree. At the undergraduate stage, students who only intend to apply for graduate students, who have not participated in the postgraduate entrance examination or have been admitted, cannot fill in "graduate students" or "graduate candidates".
In a word, the highest degree of undergraduate students in school should be "undergraduate" or "bachelor". Those who have already taken the entrance examination for master's degree and have been admitted can fill in "studying for master's degree" or "candidates for master's degree".
