Complete Step 2 CK Study Guide

"Crush Step 2" is an easy book to read. I read this twice before taking the test. I would say it has more detail than "First Aid for Step 2 CK", yet I read both of them. I thought they complemented each other well.

"NMS Review for USMLE Step 2 CK" provided a 1000 practice questions. I was able to finish the entire book. Its explanations provide a lot of background. Sometimes explanations repeat key points several times over different questions. I did all the questions once and I think it would be pretty hard to do the questions multiple times. Reading and underlining the explanations was probably where I learned the most for Step 2 CK.

"Boards and Wards" is a good pocketbook for clinical rotations as a medical student. It's also a thorough review book for Step 2 CK. I would say it's more detailed than "Crush Step 2" or "First Aid for Step 2 CK". I was able to read this 1-2 times.

"First Aid for Step 2 CK" provided good tables for the test. I read this book twice, yet I thought sometimes it provided too little detail in some areas. Reading multiple books will help the most.

I still think you need access to at least a good medical textbook, either "Harrison's" or "CMDT". Access to Access Medicine is great also. Sometimes the explanations on practice questions will need more background information. - Although many people found USMLE World to be helpful for Step 2 CK, I couldn't use it for more than 100 questions. Maybe it was because I was early in my studying or I thought the questions were too esoteric. The explanations are very detailed, and reading that much on a computer screen is not a good way for me to learn. There's about 2000 questions available.

NBME Practice Tests - The practice tests are worth the money spent on them, around $40 each. The analysis of your performance on different test areas is helpful early or even late in your studying. Their projected score was pretty accurate also.

Other Methods:
Creating your own questions helps a lot. Group studying works.

Diesel Savings Calculator

Diesel engines have become more efficient, decreased their noise, and become an alternative to gas engine cars. They can provide mileage similar to a hybrid car. Here's a calculator that will take into account the price difference between gas and diesel along with the miles per gallon difference between the two fuels. This can also be used as a Flex-Fuel Calculator to account for the lower price of ethanol fuel and difference in miles per gallon.

Hybrid Savings Calculator

Savings Calculator

Calculates the
gas money saved by buying a hybrid based on hybrid miles per gallon,
standard miles per gallon, miles driven, and gas price.

For example, a hybrid averaging 40 miles per gallon versus
a standard car with 25 miles per gallon will save $9,300 over
200,000 miles when the price of gas is $3.10.

Hybrid Gallons = 5000

Standard Gallons = 8000

Hybrid Gas Price = 15500

Standard Gas Price = 24800

Savings = 9300

Crush Step 2 CK Review

Crush Step 2 CK was a basic review for the USMLE Step 2 CK. It's a good book to read several times over before taking the boards. Although if you need help understanding a topic, it would be better to go to a more thorough source such as a textbook. The topics are organized into small paragraphs which basically list important facts. Practicing questions with a book like NMS Review for Step 2 CK is necessary to grasp concepts. I think First Aid for Step 2 CK is probably more well written although it will take longer to read.

NMS Review for Step 2 CK Book Review

NMS Review for Step 2 CK has been an excellent resource. The test questions focus on large topics that will be tested on the boards. The questions do tend to repeat several concepts but this is a good way to learn. The explanations provide adequate depth, and sometimes even provide anecdotal stories that will help you remember key points. It's well written. Questions based on pictures are limited, but the board media questions are hard to replicate. The book has about 1000 questions and it will take about 1 month to finish.

USMLE World For Step 2 CK Review

I used USMLE World for Step 2 CK for about four weeks. Although many people do highly suggest it, this product didn't work for me. I thought the questions were too detail oriented and the explanations were even more detailed. The explanations can easily fill the entire computer screen with each answer taking up to 300 words. I really stopped using the product after about 1 week of solid use. I switched to books afterwards - mainly NMS review and Crush.
