Timeline for Dependent variable is a function of independent variables; can I sensibly include them in a regression?

And I wouldn't want you to underestimate the power of partial correlation to produce very different results than you would see in zero-order correlation. You might even get a negative coefficient for one or two course grades. | |

However, in this specific case, where the response variable (GPA) is just a linear combination of the regressors (marks), my logic intuition says that the coefficients should assume values similar to the weights used for calculating GPA, so they might not be useful but they shouldn’t be arbitrary… Am I right? | |
