For that question you would have to remember that mu (u) =ln2/(number of half life days. The only one I can explicitly remember providing a formula was half life decay, At=A0*e^-(mu*t)but even then it did not specify how to use the formula. There were also some questions on interest or initial investment value that did not provide formulas. There are certain formulas that I thought they would provide, but did not like WBGT index (0.7WG+0.2GT+0.1DT). It was actually very light on math questions for the most part. Everyone learns differently though so it’s totally up to you! I would start with PocketPrep, move to SPAN, then back to PocketPrep. Only have access to the online tool for 6 months after purchase Much more difficult than the PocketPrep questions (in my opinion) but it was more indicative of how the questions were presented on the exam If you review the Workbooks they actually teach you the material (I’m much more of a learn through doing, so I would take the tests and then learn the material on the things I got wrong rather than reading the workbook as if it were a textbook) Questions were very similar to what was actually on the exam It’s not very user friendly and it doesn’t let you review incorrect answers very easily Not gonna lie, SPAN is painful to go through.
SPAN Exam Prep, CertBok online, $400 for Workbooks and CertBok online tool If you go through all questions and have an average 80% or higher pass rate, you’re guaranteed to pass or your money back Still worth reviewing all 550 questions though as they have a pass guarantee. Questions are worded more “simple” than what was on the exam Math questions were pretty consistent with what was on the exam Non-math questions were easier than what was on the exam
Out of the 550 questions, I’d say only 3-5 were actually on the exam Good for a general overview of topics and to practice quick test taking Congrats on starting the journey! It’s really not too painful.ĥ50 practice questions, very user friendly, gives you reasoning on why answers are correct
