It usually arrives as a message in the batch WhatsApp group: your physics or chemistry teacher, the one whose classes made the subject click, has left the institute. You are halfway through the syllabus, and it feels as if the ground has moved.
That feeling is normal. What matters is the next two weeks: a gap you notice early is far easier to close than one you find in a mock test.
Does a teacher leaving mid-year actually hurt your marks?
It can. In a study by Matthew Ronfeldt, Susanna Loeb and James Wyckoff, published in the American Educational Research Journal in 2013, the researchers analysed over 850,000 fourth- and fifth-grade student observations in New York City across 8 years. Students in grade levels with higher teacher turnover scored lower in both English and maths.
The detail that matters for you: the authors write that their results suggest a disruptive effect of turnover beyond any change in teacher quality. In other words, part of the harm seemed to come from the change itself, not only from who the replacement was. That study was about US schools, not Indian coaching, so treat it as a warning rather than a prediction. The useful lesson: some of the loss may be lost continuity, and you can rebuild that yourself.
What should I do in the first two weeks?
The aim is to stop the gap growing while you adjust. The tool to protect is testing yourself. In Roediger and Karpicke's 2006 experiments, students who took recall tests on prose passages remembered substantially more two days or a week later than students who simply restudied them, even though restudying made them feel more confident.
Day 1: Draw the handover line. Open your notebook and the institute's module and mark the last topic your old teacher fully finished. Note anything taught in a hurry in the final classes.
Day 2: List what was half done. For each chapter in progress, note which sub-topics were covered or skipped, and which homework sheets were never discussed.
Days 3 to 7: Test, don't reread. Each day, pick one finished chapter and do 10 to 15 questions from memory, without notes. Mark the questions you could not start.
Days 3 to 7: Fill concept holes from one source. For anything you could not start, go to the NCERT chapter first, then one reference book.
Days 8 to 14: Attend the new classes fully. Write one question per class about something you did not follow.
Day 14: Review. Compare your list of gaps with what you have fixed. Anything left becomes part of your normal weekly plan.
If the gaps add up to more than a couple of chapters, our guide on clearing a JEE or NEET chapter backlog with a triage plan shows how to decide what to fix first.
How do I adjust to a new coaching teacher?
The new teacher may use a different order, different shortcuts or a faster pace. Different is not the same as worse, so give it a few weeks before deciding anything. Speak to them early, after class or in doubt time. A script you can adapt:
"Sir/Ma'am, our previous teacher finished up to [topic] in [chapter]. [Sub-topic] was covered quickly in the last class. Could you tell me if you will revisit it, or should I cover it on my own?"
Our piece on asking better questions in class has more ways to turn confusion into a question a teacher can actually answer.
If you still cannot follow after several weeks of real effort, note exactly what goes wrong (pace, language, skipped steps) and raise it with the batch coordinator. Parents can ask the institute how the remaining syllabus will be covered and whether the earlier teacher's recorded lectures are available.
Which other resources can fill the gap?
NCERT textbooks are the usual starting point for JEE Main and NEET-UG topics, so start any gap there.
The institute's own material, such as recorded lectures, previous modules and test analysis.
Classmates with good notes from the last few classes.
An AI tutor for specific holes. The Fermi Concept Library has every concept in physics, chemistry, biology, mathematics and computing, each with its own lesson, which is useful when one idea from the half-finished chapter is missing. If you do not know where to start, Fermi's AI tutor can work out what you already know and build a plan for the session.
If the change makes you rethink coaching altogether, our guide to choosing between coaching, online classes and self-study sets out the questions to weigh as a family.
