2 Logistics -ECE242 Recommendations The goal of projects is to help you practice and master the concepts that we  see in class. Project aims at providing a rewarding and useful experience.   However , focusing your efforts only on projects will not be enough to  succeed in the 242 exams (mid-term, and final). Exams will be heavily based  on your understanding of the lecture notes, textbook, and HW practices. In order to become more comfortable with the class materials, I encourage  you to: Practice the HW before discussion  Ask questions to TA (by emails, in discussion, in Office hours) Get a complementary look at the textbook

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
