How can you get answers to your previous year’s question paper using AI?

In this article, we will deep dive on how to generate answers for any exam papers with simple, easy-to-follow steps. We will also discuss how AI technologies can be used to provide accurate answers quickly and effectively. We will also provide some tips and tricks to maximize the results.

Gathering & Extraction

First we need to collect previous year question papers of the specific exam. We are doing it for CBSE 2023 - 12th - Marketing.

Then we need to extract the text from the PDF/Image. We used Microsoft Power Toys - Text Extractor but any online OCR Software can do that.

Getting Answers using AI (LLM)

Case 1 - Multiple Choice question without prompt

First We asked the question directly to the AI In this case ChatGPT. Here is an Example

Here we can see the explanation is too long. lets try a prompt

Case 1.1 - Using a Prompt Format

We now use a prompt with format

Answer the question and follow the instructions

Q. [Question]
A. [provide only the answer]
E. [provide a very short and concise explanation]

Here we see the output is far more better then the case 1

Case 2 - Short Question without prompt

First we ask the question directly

Various entities and individuals contribute to constantly innovating and making industrial processes seamless and efficient.
Some key players in this field include:

1. **Industrial Engineers**: These professionals focus on optimizing complex systems and processes within industries. They work on designing, analyzing, and improving workflows to enhance efficiency and productivity.
2. **Research and Development (R&D) Departments**: Many companies allocate resources to R&D departments that are dedicated to developing new technologies, materials, and methodologies to improve industrial processes.
3. **Technology Companies**: Technology companies specializing in automation, artificial intelligence, data analytics, and the Internet of Things (IoT) create solutions that streamline and optimize industrial processes.
4. **Universities and Research Institutions**: Academic institutions conduct research in various fields related to industrial processes. They develop innovative approaches, technologies, and methodologies that can be adopted by industries to improve efficiency.
5. **Startups**: Startups often emerge with disruptive technologies and novel ideas aimed at solving specific industrial challenges. They can introduce new ways of doing things that lead to increased efficiency.
6. **Large Corporations**: Established corporations have the resources to invest in innovation. Many of them have dedicated innovation teams or labs focused on improving their existing processes and creating new ones.
7. **Consulting Firms**: Consulting firms specializing in process optimization and efficiency improvement provide valuable expertise to industries looking to streamline their operations.
8. **Government Initiatives**: Government agencies often support research and innovation through funding, grants, and incentives. These initiatives can lead to advancements in industrial processes.
9. **Collaborative Efforts**: Industry associations, consortiums, and partnerships between companies and research institutions can foster collaboration and innovation, pooling resources to develop efficient processes.
10. **Continuous Improvement Philosophies**: Many industries adopt philosophies like Lean Six Sigma, Total Quality Management, and Kaizen, which emphasize continuous improvement and innovation in processes.
11. **Automation and Robotics Companies**: These companies develop technologies like robotics, automation systems, and advanced control solutions that can drastically improve efficiency in various industrial sectors.
12. **Energy and Sustainability Experts**: As industries focus more on sustainability, experts in energy efficiency and environmentally-friendly practices contribute to optimizing processes while reducing resource consumption.

It's important to note that innovation is a collective effort involving a combination of individuals, organizations, and technologies working together to drive improvements in industrial processes.

Here we can see the ai is give too long answer. Let’s try a prompt

Case 2.1 - Using Word Limiting Prompt

Answer the question and follow the instructions

Q. [ Question ]
A. [ provide a answer within 30 words]

Here you can see the answer is much shorter and concise

Case 3 - Giving different types of questions

Here we give the AI a mixture of MCQ and SAQ.

(i) **Engineers or Industrial Engineers** constantly innovate to make industrial processes seamless and efficient. They work on optimizing workflows, improving efficiency, and finding innovative solutions to streamline industrial operations.
(ii) The correct answer is **(c) Workbook**. A workbook is a file containing one or more worksheets. Worksheets are the individual sheets within a workbook where you enter and manipulate data.
(iii) The correct answer is **(d) Negative thinking**. Negative thinking is not included in self-management. Self-management typically involves positive behaviors such as motivating oneself, achieving personal goals, and maintaining a constructive mindset.
(iv) The correct answer is **(a) Ctrl + P**. The shortcut key for printing a document is Ctrl + P.
(v) The correct answer is **(a) Staying positive**. Staying positive and adopting healthy coping mechanisms can help manage stress. Thinking about the past, avoiding friends, and excessive emotional outbursts are not effective ways to manage stress.
(vi) The correct answer is **(d) Social entrepreneurs**. Individuals who focus on developing solutions that benefit society, addressing social and environmental challenges, are called social entrepreneurs. They aim to create positive impact and change through their ventures.

As we can see the AI is again being too verbose

Case 3.1 - Prompt with Condition

Please note that some of the questions had options to choose from, so I've provided the correct options and explanations accordingly.

Here we see the formatting is same as we desired

Case 4 - Logical Questions

Here we ask the AI to solve some physics questions

Finding Question Pattern

For this step we have get a little bit into the technical side.

Step 1 - Formatting the Question

First we are using a LLM (Like ChatGPT) to format the question

{{ All The Questions }}

Follow the instruction:

from this questions extract every question without the index and options and put it in a array of yaml

Now save the response as “questions.yml” file using any text editor

Step 2 - Generate Vector Embeddings

What is Vector Embedding???… In simple terms it’s an physical address of a particular content (Like Image, Audio, Text, Document). Like physical addresses where similar addresses generally tends to locate in the same neighborhood this analogy holds true also for Vector Embeddings.

Note: It is generally represented using long sequence of numbers and each number range generally in 0 to 1 or -1 to +1.

Now we will use Google Colab which is a Code Execution Environment.

For this Open this Notebook - Question Embeddings.
After Connecting the Notebook in the left side of the window we see a sidebar.
In this sidebar we go to the files tab and now upload our “questions.yml” file
Now run using Ctrl + F9 Key or go-to Runtime → Run All
At the bottom we can see tensorboard window
Now In the top-right dropdown menu select projector

Voila… now you can see questions as a dot in 3D space. the more questions you have the more dots will emerge. When you have many question on the “questions.yml” (for starters at least 100, the more the better) you will see a different clusters emerge. The larger the cluster size the more common question it is.

Summery

Plain Question Vs Prompt the prompt result is always gives more concise and controlled output
In Physics Question the AI gives Inconsistent Answers. It better not to blindly rely on current AI for calculative or deductive answer
It is powerful for getting question answer in a specific format.
