Thank you so much for uploading your exam review. Your videos help me so much throughout my semester. I hope your exam review will help me prepare for my exam. I have one more chapter to go before we start our exam review. Any tips for preparing my exam and my final test?

This is a great exam review, however I do think it's a little too easy. Maybe it's just my school, but these questions seem much less complex and convoluted than I got on my tests this year. Thank you for the upload, it definitely helped with starting my review!

Hi Ms. Havrot, thank you so much for all your videos!! You saved my grade and you’re the only teacher I can fully understand!

I just did my exam and everything was so straightforward except for this one question that I can’t figure out (I don’t know if i got it wrong), and I can’t find anything online. There’s one more assignment I have to hand in, and the question comes up again in it. Could you please help me?

This is the question.

A hearing test gradually raises the nose a listener is subjected to. If the test starts with an intensity of 10⁻¹⁴Wm2, and the intensity is increased by 15% every 20 seconds, what will the average rate of change be, in dB per minute, when the dB level reaches the level of a whisper, 30dB?

Thank you so much!!
