Which Regression Model should I Use


I have a data set of students and I need to fit a regression model to predict the probability of a student will graduate college with a GPA => 3.4 or lower. I will be using age, gender, race and high-school GPA as my explanatory variables.
Do I need a logistic or linear regression and how do I set it up?

Thank you,


Less is more. Stay pure. Stay poor.
Are you planning to build the model using your data, then use that model to get the probabilities of the students used to build the model?
I need to build the model, get the coefficients and interpret them as to which ones are significant in predicting the graduating GPA being over 3.4.
