The whole of MBBS, mapped against Step 1 — what to do in each year, what to ignore, and the one habit that makes all four compound instead of evaporate.

How should I prepare for USMLE Step 1 year by year during MBBS?
Treat MBBS and Step 1 as one syllabus, and make sure every extra point goes into the First Aid page, never a separate notebook. In first year, build physiology, anatomy and biochemistry with First Aid open alongside. Second year is the most valuable: microbiology with Sketchy first, then pathology system-wise, then pharmacology. Third year is either your exam year, on the 24-week plan, or consolidation. In final year, work system by system, then do UWorld until your last 2 blocks hold above 65 to 70%.
Almost everyone treats MBBS and Step 1 as two syllabuses. They are not. The pulmonary medicine you are taught on the wards is the respiratory pathology in First Aid. The antibiotics your professor drills you on are Sketchy Micro. The difference is format and vocabulary — Step 1 asks it as a vignette, your university asks it as a viva.
Which means the question was never "when do I find time for USMLE." It is "which book does today's studying land in."
Systems, delivered daily by people paid to teach them
Look at the second year row again. Pathology, pharmacology and microbiology are simultaneously your university syllabus and the three largest content blocks on Step 1. That single overlap is the entire opportunity, and it happens whether you use it or not.
Year 1 — build the foundation once
You are not "starting Step 1." You are building basics that happen to be Step 1. Same hours, twice the return.
🫀
Physiology. Guyton as your standard textbook, Dr. Najeeb for what Guyton assumes you already know, and First Aid open to that same system alongside them — not afterwards.
🦴
Anatomy — and flip the order. Start from First Aid with the First Aid Guide, then read your standard textbook. You will already know which structures are tested, so the reading is targeted instead of infinite. And do neuroanatomy from Najeeb this year — it is the best thing you will do all year, and the reason CNS will not break you later.
🧬
Biochemistry needs nothing extra. Every topic in your university textbook is already in First Aid. There is no separate USMLE biochem syllabus to add.
Year 2 — the most valuable year you will ever have
Three subjects, in this order. The order is not negotiable, because pharmacology makes no sense before pathology.
1
Microbiology — Sketchy, first. ~85 organisms over six days, video then PDF, and that day's MCQs the same night. Watch then test. I was still using this knowledge in residency in 2026. The 6-day order →
2
Pathology — system-wise, never as one subject. Pathoma first (understand, do not memorise) → First Aid topic by topic with the Guide → Robbins last, deliberately, so the textbook reading is targeted. Three to five days a system.
3
Pharmacology — after pathology. It is not hard, it is disorganised. Get the map of which drug from which resource, then watch each video twice. Five to six days a system. The FWRT method →
This is where the paths split, and the split is worth understanding before you are standing in it.
🎯
Giving Step 1 in third year? Then third year is not where you learn it — it is where you assemble it. Twenty-four weeks: two weeks foundation, sixteen weeks of systems, six weeks of NBMEs. The full 24-week plan →
📚
Not yet? Then third year is consolidation. Keep annotating into First Aid, keep the Foundation Anki deck running on systems you have already covered, and protect the habit. Your exam year is final year or internship.
Final year — the overlap is total
Final year is the only year where your college syllabus and Step 1 overlap this completely. Medicine, surgery, paediatrics and OBGYN, delivered daily, by people paid to teach them.

Eleven systems, about ten days each, plus twenty buffer days. Micro on day one → First Aid with the Guide → your lecture platform (Marrow, DAMS, PrepLadder — whichever you already pay for) → Mehlman in one day → Anki the next → then UWorld until your last two blocks hold above 65%. About four months of systems.
Every extra point you learn goes into the First Aid page. Never into a separate notebook.
Do that from first year and you finish MBBS with one book that holds your university syllabus and your Step 1 syllabus at the same time — and you revise it once.
Skip it and you finish with lecture notes for college and First Aid for USMLE, which means you studied every year twice and now have to revise it twice. That is the whole difference between the people who need four months for Step 1 and the people who need two years.
And First Aid does not teach. It was written to remind, which is exactly why students bounce off it in first year. The First Aid Guide decodes all 646 pages — the best video for each topic already attached, an ELI5 explanation, how the page is tested, and MCQs on that exact page. See a real page →
