Only include your GPA if it is higher than 3.5 on a 4 point scale (no need to mention that 2.0 when you moved into the frat house sophomore year) and only if you are a recent graudate. There are a few exceptions to this rule, like if you’re applying for a job in academia or engineering where a GPA is expected. You can also list honors or awards if you’re a recent graduate. If you attended college, but did not finish your degree, list the number of credits obtained. For recent graduates, education and internship are your main selling point. But if you’ve already been in the workforce, tone down your education section, the best rule of thumb is that one line will suffice.
There is not one resume format that works for everyone. There might not even be only one resume format for you and it could benefit you to have multiple formats of your resume available. For example, if you’re applying for a job and you don’t know whether your resume will be submitted through ATS, submit both a chronological resume and use a functional resume for your in person interview.
