If opportunity doesn’t knock, build a door.

Welcome back to Episode 14! After a short break for Jeff’s honeymoon, we are back this week with more high-quality review. We have weekly episodes in the works to keep you motivated. Take note of a small change to the format this week: after each question, you will hear a one-second pause to contemplate the answer or to pause the podcast to give you even more time. We made this change in response to listener feedback; keep more feedback coming to Roshcast@roshreview.com

We have one more exciting change to announce this week. As you go through the Rosh Review EM question bank and you come across a difficult question or a question you think would be perfect for Roshcasting, hit the “submit feedback” button and type “Roshcast.”

Submit feedback

This will prompt the feedback to alert us, and we will work on incorporating the question as quickly as possible. Let’s get started with this week’s episode.
