Someone asked this question on Yahoo Answers.

Is fundamentals of Applied Nuclear Physics class HARD?
(I thought that question was amusing, considering all the other classes this guy had taken, as he describes below:)

I'm studying Electrical engineering (Junior ) and planning to take Nuclear engineering as Minor. I have to take three courses in order to have this minor. I don't know if these classes are hard. the three classes are :
first one focus on " introduction to quantum mechanics, nuclear forces and nuclear structure, nuclear stability and reactions, natural and induced radioactivity"

Second class is Introduction to Radiation Physics and Dosimetry
Third class is Introduction to Nuclear Engineering.

I have completed many math classes (Cal 1,2, Linear algebra and DE)
I took Physic last summer (Waves, Optics, & Thermodynamic)

He only received one answer, not surprising considering the fact that he was asking this question on "Yahoo Answers."

You have all the background you need; work as hard as you did in your previous courses and you will succeed.

But the answer is correct.
