completely depends on your curriculum.
B&B + Zanki is good. IMO light year has too many repeats and zanki has more material in it. FA is a nice reference material that I didn't find helpful for first year. Buy USMLE-RX and use it along side your classes. You can study the material all you want, but until you see practice questions and how the material will be asked, you probably don't know it as well as you think you do. IMO you should save Uworld until dedicated.
Things to keep in mind:
1) don't forget to focus on yourself. You really shouldn't be sacrificing sleep for studying unless its the night before an exam or something crazy happened earlier and you couldn't study. Even then more sleep > cramming for 3 hours before the exam after waking up at 3 am.
2) Come up with a realistic schedule and stick to it. Schedule in off time and time to exercise. You probably will have more time than you thought, make sure you have time for hobbies. Do you play video games? Great, totally acceptable to play for an hour or two a night if you are caught up on studying. Golf? Rock climb? Swim? Perfect, go do it. Studying for 15 hours a day every day in 1st year is the best way to burnout in a month and destroy your mental health.
3) don't compare yourself to others. people will probably talk about how they're disappointed they "only" got a 92%, or constantly say "I didn't study at all and like omg i'm going to fail" when you know for a fact they spend 10 hours a day in the library. Ignore it.
4) Try to meet as many people as you can. It's kind of like freshman year of college all over again. Except much smaller. These are the people you're going to go through hell with for the next 2 years. It *really* helps when you have close friends, study partners, and people to go do things with on a friday/saturday night. I know for a fact I couldn't have made it this far without my friends
5) Have fun. Medical school sucks some times, but I've really had an amazing time so far.
Before anyone replies with "AKSHUALLY porkchopsog, you're wrong" and completely refutes everything I've said, note that it's all personal preference and you have to do what works for you. I'm someone that needs more sleep and off time: I sacrified some study time for that, and I'm really glad I did. once you find what works for you, stick to it!
