We have been hearing a lot about “Flatten the curve” recently. Graphical interpretations and plotting of data have helped us a lot during the Pandemic time.
So this year we can expect more weightage for Graph-based questions in NEET 2021. Every year in NEET, a minimum of 3 Graph-based questions are asked which means 12 marks straight onto your scorecard.
Most of us think that Graph-based questions are only from Physics but interestingly Graph-based questions from Chemistry and Biology do come up for the NEET exam. The exam conducting authority can ask both direct and indirect questions from graphs in order to test the application knowledge of students rather than fact-based recalls. Let us now look into a few important points regarding Graph-Based questions.
What do you need to know about Graphs?
When you come across any graphs it is important that you note the following details:
- Shape / Nature of the graph
- Slope of the graph
- X and Y components
- Area under the curve
These are the four basic points to be kept in mind when you deal with graphs.
Where can you Expect Graphical questions in NEET 2021?
We can expect graphical questions from all three subjects namely, Physics, Chemistry and Biology. In order to know the different kinds of graphs asked for NEET, all you need to do is solve as many previous year questions as you can.
From Biology, following graphs can be expected:
- Variation of enzymatic activities with temperature, pH
- Variation of rate of Photosynthesis with changes in Light intensity
- Growth curve of plants- Linear and Sigmoid
- Menstrual cycle hormone levels
- Types of natural selection (Hardy Weinberg Principle
- Species area relationship
- Organismic responses
- Population growth curve
- Effect of sewage discharge on rivers
From Chemistry, following graphs can be expected:
- Graphs for zero, first and second-order reactions
- Graphs for Boyles law, Charles law, Gay Lussacs law, Avogados law
- Ideal gas versus real gas comparison graph
- graph for Henry’s law
- graph for all the cases of Raoult’s law
- graph for depression in freezing point and elevation in boiling point
- trends of molar conductivity with concentration
- Freundlich isotherm

From Physics, the following graphs can be expected:
- Electric field versus distance
- Potential versus charge of a capacitor
- Variation of current with a potential difference
- Variation of resistivity with temperature
- V versus L graph for potentiometer.
- All graphs for LCR circuits.
- Graphs under the topic dual nature of matter
- Decay curve
- Diode characteristic curves
The list would continue as the scope to have graphical questions is immense.
The best way to score well in graph-based question is to not miss out on any graphs in the NCERT textbook and to practice as many questions as possible from Basidia Learning App. As we have 33,000+ MCQ’s which have detailed solutions hand-picked from the previous 10 years of NEET-UG, AIIMS and AIPMT question papers.
