You know what the exams always ask, the wording is the tricky part.
Yeah test anxiety is real deal..I KNOW 1st hand...but i believe every place i've taken the exam offers more than 1 chance, so that should relieve some "pressure", however there is a difference between not knowing the material & exam anxiety.
The NUF is NOT about being "smart" it's about knowing the material.
The practice exams on this site are very helpful, IMO, but are no substitute for the material from Westrain. I believe this site had a condensed version of some typical questions that are asked on an exam.
HERE.
IE something like 16 N activity is the primary source of radiation fields in the BWR coolant.
know 6 CEN thats an easy point..
Air sample calc is another easy point & always on there.
A decay question is pretty standard too..
know how to figure a 1/2 life question ...which can be worded kinda crappy sometimes..
Point soucre is another gimme esp if you can use a distanance factor..
And lastly you have to know instruments well enough to be able to recognize the answer on the exam.
Also remember..You don't get anything extra for 100% on the NUF but if you get an 80% you get the job! IE.. 80=100
