Emmaline Brooke Posted over 1 year ago Should the grades earned from institutions matter when applying a job? it depends on the kind of job. for example, if you are applying for a job that requires for a great deal of academic knowledge, it's probably a need to have good grades. then again, if you a apply for a job that doesn't require that much of academic knowledge, then your GPA shouldn't really matter. however, that also brings up the debate about your ability to concentrate in school and in your career life.
