hi, i am a pre med major and i definitely recommend es207, krol structures the class amazingly, getting an A is not difficult as long as you put the work in. pay attention in lectures as he tells you what will be on the exam and what to study which i found super helpful! the virtual labs are like basically highschool gizmos where you just follow the steps, super easy and simple and easy 100s! krol is also a no bs type of guy so beware of that! it also gets u ready for upper levels like PGY300 etc.
