As an Architectural Engineer, I am usually stuck in class about 32 hours per week- as you can imagine, in conjunction with time for homework this really leaves me with very little time to go to office hours for each of my individual classes. I used PSU Knowhow for a 'consolidated office hour' of sorts to ask in depth questions on the minutiae of the 7 classes I am currently taking, and it was a very beneficial experience. Whether you have specific questions you need answered from a myriad of courses and don't have the time to go to each individual classes' office hours, like I did, or need instruction for just one course, Jeremy certainly has the ability to do both very well.
