Vishal,
I'm glad you made the comments about only a few steps and if the problems were 'tricky'.
I have a very limited amount of study time and starting to feel that a lot of the MERM questions are too in-depth, even when considering they are in parts. Also, a significant amount of the review material in the MERM is also not a good use of time (if push comes to shove). The MERM is talked about as "over preparation" but I wouldn't describe it as so, but would say the over preparation is in a way that does not really help you. Don't get me wrong, I'm glad to have the MERM and would recommend to anyone, with the above info. I would prefer more questions about understanding the principals involved and less math. That way you can be challenged with dozens of questions instead of a few big number crunchers.
I took a quick peek at the NCESS practice exam and was totally shocked at the simplicity of a few of the problems (could be answered as quickly as you could read the problem, with no look-up), but I was also aware that some of the very simple problems require in-depth knowledge of the topic, but very little number crunching.
Away, thanks for the comments,
BH
