Chronicles of a Med Student: And So It Begins!
The minute the tasseled hat flew off of my head after “Pomp and Circumstance”, I knew I was no longer a kid. What a startling realization–one I’m sure many of you have experienced–for someone who has led a fairly sheltered life! Let me confess one little thing: I was scared. Not just an ordinary level of scared. The kind of scared that catches you by surprise to the point where you start bawling on your graduation day with your bedazzled cap and a brand new bachelor’s degree in your hand. I was taking a gap year and had no idea which direction my life was going to go next. I knew what I had been working for my entire life: medical school. But this was not the feeling I had anticipated when I completed my undergraduate career. I had practically planned my life out since I was in middle school: I was going to go straight from high school to college to medical school to a career. But things had changed; I had grown a little tired of the academic life and wanted to experience something new. I wanted to live a little! But figuring out what to do next and how to do it was intimidating.
10 Signs You're an Intern
1. 2 Days off in a row = Vacation!
In high school, I looked forward to winter break, spring break, and summer break. In undergraduate, it was the two weeks off over winter break and the week off between quarters. Anything short of a week off felt like barely time to catch your breath – definitely not a vacation. As a medical student, there was still winter break and most bank holidays. Now, as an intern, any time there are two days off in a row, what most of the rest of my non-medicine peers would simply call “the weekend” constitutes the most luxurious vacation.
5 Things You Should Know About Secondary Applications
Unlike other graduate school admissions processes, where there is typically only one round of applications, medical schools often have a primary application and a secondary application. The secondary application generally involves one or more essay questions that are meant to help the admissions committee better understand your background, qualifications, and career aspirations. Below are five things you should know about medical school secondary applications.

5 Reasons Intern Year is Better Than Medical School
I had a certain level of (I thought well-justified) terror anticipating the start of intern year. No longer able to hide behind the protective “I’m just the medical student” blockade, I was worried about not being able to live up to the burden and the privilege of being someone’s doctor. Third year was rough and I could only imagine the horrors that awaited me as an intern. Yes, it has been a difficult year, filled with long hours and intense days. However, what I found was that contrary to my fears, intern year has been so much better than medical school. If you recently walked across the stage and accept your diploma, congratulations! Here’s what you have to look forward to:

5 Mistakes I Made in Med School (So You Don’t Have To)
It has been nearly a year now since I walked across the stage at Carnegie Hall to accept my diploma. Now approaching the end of internship – let’s say that again, one more time, with appropriate emphasis: the end of internship – I can look back with a little more objectivity on my four years of medical training. As with everything else, hindsight is mostly 20/20 and, while there are a lot of things I did right in medical school, I now realize I made some mistakes, or, if they weren’t outright blunders, at least things I would do differently if I had to do it again. Let that these not be your mistakes:
Is Summer MCAT Prep Right for Me?
Preparing for the MCAT during the summer months is a choice that many pre-medical students make – and for good reason. Summer prep provides several advantages over simultaneously juggling coursework with MCAT review during the school year. However, students should also understand that summer prep can be more difficult in certain situations. Below are four questions to consider when debating whether or not to prepare for the MCAT over the summer:
1. Are you able to effectively multitask and prioritize?
One significant difference between preparing for the MCAT during the school year versus preparing for the MCAT during the summer is that summer prep often allows you to focus solely on MCAT review. Studying for the MCAT during the academic year – while also taking courses and participating in various extracurricular activities – requires well developed time management and prioritization skills.
If you currently struggle to manage multiple commitments during the school year (as is common for many pre-medical students who are stretched quite thin), then you may benefit from preparing for the MCAT during the summer months. Free of distractions, you will be better able to truly focus on this crucial exam.
How We Found Our Voice As Hospitalists
Approximately a year ago, our CEO hired a healthcare performance company to evaluate our hospitalist group’s performance and make recommendations as to how to cut costs and improve efficiency. What soon followed was a Request for Proposal (RFP) which was released in the summer of 2014. Our CEO was searching for a third-party company to take over management of our hospitalists and save our non-profit corporation the cost of employing and managing the hospitalists. Needless to say, this was more than upsetting for the 37 employed hospitalists. Were our jobs secure? Were we going to be fired and have to apply to be hired by this third-party corporation if we wanted to stay in this community?

Tips from the Trenches: 5 Tips for Surviving Intern Year
Dear Incoming Interns,
Congratulations on matching and reaching the end of medical school! I am sure you are very excited to be graduating, and we interns are equally excited for you as it means we are about ready to say “so long” to our intern year. (Right now, I have 62 clinical days left – but who’s counting?) Intern year is one steep learning curve after another. Just about the time you figure out a particular service, you switch to the next. Over time, however, themes emerge, the transitions become easier, and the mass of random lab values, medications, signs and symptoms, slowly gel into cohesive patient narratives. Below is some of my own hard-earned advice from this year, some practical, some personal.

Picking the Right Medical School Program
There’s a popular phrase, “If you’ve seen one medical school… you’ve seen one medical school.” Every school is completely different, so it’s a good idea to thoroughly research what programs would be best for you before you start the application process.
What are you looking for?

When you’re deciding which medical schools to apply to, consider some of the same factors you weighed when applying to college: Are you looking for a public or private university? Do you want to attend school in your home state or out-of-state? You may also narrow your choices by considering the specialties offered or even which clubs and organizations are available to med students.
