How to Study for Medical Residency with Sintesy (Without Wasting Hours Taking Notes)
You’re halfway through an Internal Medicine lecture. The professor has already covered three differential diagnoses, two classifications, and a flowchart. Your hand aches from writing — and you still haven’t absorbed half of what was said.
That’s the pace of a medical residency prep course. You’re looking at 800 to 1,500 hours of lectures spanning five major areas. While you’re jotting down one thing, the professor has already explained three more. By the end of the day, you have a full notebook and a mind that doesn’t know where to start reviewing.
Sintesy solves this problem at the root: you record the lecture and get a ready-to-use study guide, with topics organized in the exact order they were presented. No typing. No note-taking. No losing the thread.
The Scale of the Challenge
The 2021 ENARE (Brazilian National Residency Exam) drew over 42,000 candidates competing for roughly 3,200 spots — a ratio of 13 candidates per slot. And that’s just one exam. Those sitting for USP-RP, UNICAMP, SUS-SP, or AMRIGS face a content volume that can exceed 15,000 pages of material.
Faced with this, most students spend 30% to 40% of their study time on passive note-taking. Four hours of lecture become another two or three hours organizing the notebook. It’s an unpaid second shift — and worse: taking notes is not studying.
Why Note-Taking Hurts More Than It Helps
There’s a big difference between recording information and learning it. Note-taking during a lecture engages short-term memory — you write, but you don’t process. Content goes in one ear, through your hand, and evaporates.
The Ebbinghaus forgetting curve shows that without active review, we lose about 50% of content within a few days. After a week, less than 20% remains. If you spent the lecture taking notes, the material you should be using to review isn’t even ready yet — and the forgetting curve clock is already ticking.
The techniques that actually work — active recall and spaced repetition — are two to three times more effective than passive re-reading. But they depend on one thing: content that’s already organized. You don’t make flashcards during a lecture. You make them afterward. And if “afterward” means first spending three hours cleaning up your notes, the flashcards never get made.
How Sintesy Fits Into This Workflow
Sintesy eliminates the note-taking step entirely. The workflow is simple:
1. Record the lecture audio
Open Sintesy on your phone or laptop and let it record. No special microphone needed — the audio from your prep course or university lecture works fine. You can record in-person lectures, online classes, or even that WhatsApp audio a classmate sent with the professor’s explanation.
2. Generate the study guide
When the lecture ends, click generate. Sintesy transcribes the audio, identifies the content structure, and organizes everything into sequential topics. Each theme becomes a section. Each section keeps the original lecture order.
3. Review with ready-to-use material
You receive a document with topics separated and organized. It’s not raw transcription — it’s a study guide. You can re-read in 15 minutes what would take two hours to clean up by hand. And best of all: you already have the content ready to create flashcards, mind maps, or whatever you prefer.
What Changes in Practice
| Before (without Sintesy) | After (with Sintesy) |
|---|---|
| 4h lecture + 2h note-taking | 4h lecture + 0h note-taking |
| Disorganized notebook | Structured guide by topic |
| Review delayed for days | Content ready in minutes |
| Focus on writing | Focus on understanding |
| Flashcards? Only on weekends | Flashcards the same day |
The real gain isn’t just in the hours saved. It’s in starting your review the same day — before the forgetting curve takes half the content with it.
Which Subjects Work Best
Sintesy works especially well for subjects with high volumes of lecture-style content, which makes up the bulk of the clinical cycle and residency prep:
- Internal Medicine — differential diagnoses, classifications, flowcharts
- Pediatrics — developmental milestones, vaccination schedules, prevalent diseases
- Surgery — indications, techniques, complications
- Obstetrics & Gynecology — prenatal care, delivery, obstetric emergencies
- Preventive Medicine — epidemiology, surveillance, health policies
Across all of these, the pattern is the same: a professor talking for hours while you try to keep up. Sintesy does the keeping up for you.
What If the Lecture Is in English?
A lot of study material for residency — articles, video lectures, conferences — is in English. Sintesy transcribes and summarizes in Portuguese, regardless of the audio language. You record an English-language lecture and get the study guide in Portuguese.
How to Get Started
- Go to Sintesy on your browser or download the app
- During your next prep course lecture, open Sintesy and start recording
- When it’s over, click generate
- In a few minutes, your study guide will be ready
No configuration. No prompts. Just open, record, and receive.
Studying for residency isn’t about who takes notes the fastest. It’s about who reviews best. Sintesy gets note-taking out of the way so you can focus on what really matters: understanding, retaining, and applying.
