I took Econ 1. The teacher is very clear in her explanations. You must know everything that she lectures on though. The 2 assignments were easy. The midterm and final were very challenging for me. The TA's can be helpful, but I'd recommend seeing the prof directly. Make sure you take very good lecture notes and attend every lecture. I did not find the book very helpful. Overall, a challenging course but manageable if you stay with it.
