INBDE Study Techniques That Work: Active Recall, Spaced Repetition and Timed Focus
The two study techniques with the strongest research behind them are testing yourself (active recall) and spreading your reviews out over time (spaced repetition). For the INBDE, that means learning from questions instead of rereading, reviewing every wrong answer, and meeting missed material again on a schedule. Timed focus blocks then build the stamina a 2-day exam needs. The Study Boards INBDE course is built on all three, so you practise them every day without having to set anything up yourself.
The techniques are already built into your course
You do not need to build a review system of your own. In The Study Boards INBDE course, active recall happens through your daily tasks, the nightly live test at 9 PM New York time and the Master and Grand Test Series. Spaced repetition happens because red lines and assignments come back to you on the go, and the course learns from the way you are studying. We train you in timed focus blocks that grow into full 105-minute sections, and our faculty, Dr. T and Dr. Kaur, are there to assist you whenever you get stuck. See the full structure in The Study Boards INBDE course blueprint.
What the research actually shows
Most dentists prepare the way they studied at university: read, highlight, reread. The research points somewhere else, and we built our INBDE course on the findings below.
Students studied prose passages, then either restudied them or took recall tests. On a test 5 minutes later, restudying did better. On tests 2 days and 1 week later, the students who had tested themselves remembered substantially more. Restudying also made students more confident, even though they remembered less.1
For you: the smooth feeling of rereading notes is not a sign you will remember them on exam day.
Five learning scientists rated 10 techniques on how well their benefits hold across learners, materials and test types. Only two were rated high utility: practice testing and distributed practice.2
| Technique | Rating | Where it sits in our course |
|---|---|---|
| Practice testing | High | Daily tasks, the nightly live test and the test series |
| Distributed practice | High | Red lines and assignments that bring missed topics back days and weeks later |
| Elaborative interrogation | Moderate | Asking “why is this true?” while you read each explanation |
| Self-explanation | Moderate | Explaining why each wrong option is wrong |
| Interleaved practice | Moderate | Mixed-subject tests after the first pass through the modules |
| Summarization, highlighting, keyword mnemonic, imagery for text, rereading | Low | Use sparingly; replace rereading with testing |
A meta-analysis of 839 comparisons from 317 experiments found that spaced study beats massed study, and that the gap giving the best retention grows as the time to the test grows.3 A follow-up study of more than 1,350 people found the best gap was about 20 to 40% of the time to the test when the test was 1 week away, falling to about 5 to 10% when it was 1 year away.4
For you: the further away your exam, the longer you can leave between reviews.
Multiple-choice tests can plant wrong answers: students sometimes remember a wrong option as true. Feedback, immediate or delayed, raised correct answers and reduced those wrong-option errors on a later test.5
For you: a question block without careful review can teach you the wrong thing. That is why every question in our course comes with a full explanation.
At a medical and dental college in Karachi, 115 final-year medical students studied pediatrics for four weeks either with books and lectures or with spaced-repetition review. The spaced-review group’s average rose from 27.9 to 30.8 out of 50; the traditional group did not improve.6
Active recall: how the course makes you retrieve, every day
Active recall means pulling an answer out of your memory before you see it. In our course, the daily tasks, the nightly live test and the test series all do this. Here is how to get the most from every question.
Review wrong answers, then space the redo
Your wrong answers are the most valuable pages of your preparation. Review them by cause, then meet them again on a schedule.
| Why you missed it | What it looks like | The fix |
|---|---|---|
| Did not know | You had never seen the fact or rule | Learn it from the subject module, then redo the question later |
| Mixed it up | You confused two similar things (two lesions, two drugs) | Make a two-column comparison of the two and redo both questions |
| Misread | You missed “except”, “first”, “most likely” or a detail in the case | Underline the key word on your noteboard before answering |
| Changed a right answer | Your first reasoned answer was correct | Only change an answer when you find a specific fact that proves it wrong |
| Ran out of time | You guessed the last questions in a block | Practise at about one minute per question (100 questions in 105 minutes); read INBDE time per question |
When to redo a missed question
Redo every miss the next day, then again after a longer gap. Pick your exam distance to see our working rule.
- Day 1: redo in your morning warm-up.
- Then roughly once a week until the exam.
- Final pass: all “did not know” misses in the last 5 days.
- Day 1: redo in your morning warm-up.
- Then every 1 to 2 weeks; drop a question after two clean redos.
- Final pass: all remaining misses in the last 2 weeks.
- Day 1: redo in your morning warm-up.
- Then every 2 to 3 weeks; drop a question after two clean redos.
- Final pass: all remaining misses in the last month.
These gaps are our own rule of thumb, read off the pattern in the 2008 spacing study (longer gaps for later tests, but a smaller share of the time left). They are not numbers the study tested for the INBDE.4
Spaced repetition: how the course brings topics back to you
Spacing only works if missed material actually comes back at the right time. In our course, you do not have to track that yourself.
Daily tasks for the dayEach day starts with a set task list, so new learning and review are planned for you. You open the course and know exactly what today’s work is.
Red lines and assignments on the goRed lines and assignments are given to you on the go, based on what you are getting wrong. Weak topics come back to you instead of waiting for you to remember them.
A course that learns from how you studyThe course learns from the way you are studying, so the material that returns is the material you need. This is what makes our courses extremely personalised.
Test series that revisit every subjectThe nightly live tests, the Master Test Series and the 8-hour Grand Test Series mix subjects, so every topic is tested again weeks after you first studied it.
Your daily checklist inside the course
Timed focus blocks, built up for a 2-day exam
Short, timed work blocks with fixed breaks (the idea often called the Pomodoro method, usually 25 minutes of work and 5 of rest) are a good way to start a study day. We train our students in timed focus blocks inside the course, and we stretch them until they match the exam.
In a 2023 study, 87 university students either took breaks whenever they chose or took fixed breaks (6 minutes after every 24 minutes, or 3 after every 12). Students who chose their own breaks studied and rested longer, and reported more fatigue and distraction and less concentration and motivation. All groups completed similar amounts of work, so fixed breaks got the same result in less time.7
The INBDE asks for much longer focus: each section runs 105 minutes, Day 1 lasts 8 hours 15 minutes with scheduled breaks of 15, 30 and 15 minutes, and Day 2 lasts 4 hours 15 minutes.8 So the blocks we train you in grow as your exam gets closer.
| Stage | Work block | Break | What you do in the course |
|---|---|---|---|
| Learning a subject | 25 minutes | 5 minutes | One module topic, then blank-page recall |
| Question practice | 50 minutes | 10 minutes | About 50 questions from your daily task, then a short break before review |
| Exam-section training | 105 minutes | 15 minutes | 100 questions in one sitting, like one INBDE section |
| Full rehearsal | Four 105-minute sections | 15, 30, 15 minutes | An 8-hour Grand Test for Day 1, then Day 2 with two case sections |
To see how these blocks fit into one day, follow the daily blocks in our 6-week INBDE study schedule. For full simulation advice, read how to take INBDE simulation exams.
Three quick questions
1. You reread your pharmacology notes twice and feel confident. What does the research predict for a test a week from now?
2. You finish a 100-question block and only check your score. What is the risk?
3. Your exam is six months away. Should you redo a missed question every day?
