More disturbing errors throughout this text. Such as a failure to understand how hypothesis are written. The practice test #3 question #14 states that a hypothesis must be an if/then statement in order to be testable. No science teacher should be teaching that. You can have a null format or a directional format and still have a testable hypothesis.

More errors - this time in the practice tests. They stated that the work done is equal to the change in potential. This is incorrect. Work done is equal to the negative change in potential. I'm starting to think these materials are not only woefully inaccurate, but also not like the exam at all.
