Reviews
This study guide is tailored to Physics 7B with Professor Bale and contains lecture notes, practice problems, and old exams with step-by-step solutions.
If you find yourself not knowing how to study or what to focus on when you leave discussion and feel like you could use some help with the class, then this study guide is a great resource. Not only will it teach you what you need to know to do well on exams, it will also save you massive amounts of time otherwise wasted on trying to find relevant problems with good solutions.
I have spent over 15 years helping students with Physics and I look forward to helping you do well in Physics 7B!
