Current MS1 (just finished,,,starting MS2 now). Some advice
1. It's okay to be nervous. Everyone is. Whether they show it or not. I took 3 gap years, 3 MCATs, and worked my tail off to get in. I was a nervous wreck sitting next to students that did a BS in 2.5 years and scored 99th percentile MCAT. Don't fret
2. Anatomy isn't the end all, be all. Medical school gets tremendously easier afterward
3. Don't waste time with toxic people. There will be students gunning from day 1. "Oh. you went to <small liberal arts school?> I just graduated from Cal Tech with a triple major of BME+Comp. Sci+ Pharmacology in 3 years. My dad is also dept. chair of IM and my mom is hospital president." Don't waste time with losers like this.
4. Enjoy yourself. Believe it or not, medical school is not 24/7 studying. It may seem that way at the beginning, but as you get better with studying and time management, you will have time for your hobbies. Go to the gym, play your instrument, socialize, cook, do yoga, etc. Its all good in the end.
Any specific issues, feel free to DM me, wishing y'all baby MS1s good luck ^_^
