Quarter+2+Striving+for+accuracy+and+precision

Looking back at test on unit 1 i made several careless mistakes. I rushed through the test and didn't do very well. Some of them are shown below





number of neutrons was suppose to be 14 positively charged nucleus was more precise and better fit of a description it was suppose to be group not period

This taught me a lesson about not rushing and checking over what i wrote. This wasn't the first time i have seen mistakes like this. It happens in my other subjects too. I think the main reason is because i was sleep deprived. I improved on careless mistakes on the second test. There were less mistakes like that since i took the time to look over it although i still missed some probably because i did not have sufficient sleep. I also tried to be more precise in what i wrote. Moreover, it may also be due to my state of mind, especially during tests i can tell by looking through the test at the start and then get a sense of how i will do depending on how i feel.
