Getting an A in my class comes down to one simple task. 
DO THE WORK!!!

 

If you do the readings and participate in class, you will find that you can earn an A or B without a problem.  Students that have struggled with this class do so because they choose not to study.  Physical Science is an introduction to two very difficult sciences.  Study and you will amaze yourself.  Don't and you will struggle.  Several nights a week, you will have readings. 
Complete these reading, define any vocabulary words
and
you will have no difficulties getting a 100% on the quiz that
will follow the next day. 
The quizes are designed to test your completion of the homework and your preparedness for the days lesson therefore, your quiz will be given prior to the lecture for the day. 

Come prepared, and you will be assured an A.  Come unprepared, and the only person you have to blame is yourself!!!
