Unit 2 Pre-test

The pre-test that we took on Tuesday was really difficult. I didn't know the majority of the answers. However, on some of the questions, I was able to use prior knowledge of chemistry to make an educated guess. Also, as I continued I recognized that there was probably a pattern in the questions with the atomic masses and etc. The test also included sections where I had to read and answer questions about graphs which wasn't as hard as the rest of the test because we were able to use prior skills of reading scientific graphs.
