What is the job of a data scientist? 

Before becoming something or someone, you must know what that profession stands for. Before you decide to become a data scientist after 12th, make sure you know what a data scientist does. A data scientist is an individual who studies big piles of information, known as data. They use it to find patterns and help brands and industries make better and smarter decisions. This might include predicting sales trends, understanding consumer behaviour, or developing tools that can automate particular business tasks.

Data scientists combine mathematics, statistics, and computer programming and use that mix in their everyday work. They usually work closely with other corporate teams such as marketing, finance, or product development to convert original and unorganised data into important and organised insights. 

How to become a data scientist after 12th?

Here comes the main question that most students or learners ask. The answer to this is that you cannot become a complete data scientist urgently after completing your 12th. This career path asks you to have a bachelor’s degree, along with strong technical skills built through practice and real-life projects. 

However, immediately after the 12th is the accurate time for you to start preparing. Choosing the right subjects, a suitable degree, and useful key skills can result in walking towards the right way to become a data scientist by the time you complete your graduation. 

The following are some easy and important steps for you to become a data scientist:

Step 1: Choose the suitable subjects in 12th grade

If you are currently in school or you are about to start your final years, one of the most important things is the subjects that you choose. The students who are trying to figure out how to become a data scientist after 12th must have a strong background in mathematics. 

The following are the subject combinations that you can choose from:

• Science stream with Mathematics – It includes physics, chemistry, and mathematics (PCM), which is a strong and common choice.
• Commerce with Mathematics – This path is also a valid path, specifically if it is paired with strong coding and statistics skills later. 

If you are someone who has already completed your 12th without mathematics, you do not have to worry too much. Many universities offer foundation or bridge courses in basic mathematics and statistics for students who need to catch up before beginning a full data science programme. 

Step 2: Pick the best bachelor’s degree

When you have completed your 12th, the next main step is to choose a bachelor’s degree. This is one of the cleanest and most direct steps in the entire process. Your degree puts the foundation for everything that follows: 

The following are some of the firm degree options: 

• B.Tech or B.E. in computer science, along with a data science specialisation
• B.Sc. in Data Science, Statistics, or Mathematics 
• BCA (Bachelor of Computer Applications), specifically if it is paired with strong self-learning in data-related skills.  

The majority of these degree programmes last for 3 to 4 years, but it depends on the course and country. At this time, you will be studying subjects like programming, statistics, probability, and usually an introduction to machine learning. 

Step 3: Learn the basic technical skills

Having a degree is not enough; you must know the skills required for a data scientist. Employers want data scientists to have hands-on technical skills, many of which you can start learning during or even before your degree programme. 

The following are the major skills to focus on:  

• Programming languages – Learning programming languages is a must to become a data scientist. The most widely used programming languages are Python and SQL 
• Statistics and probability – Statistics and probability are the subjects that create the backbone of the majority of the data analysis and prediction work.

• Data handling tools – Learning data handling tools means learning how to clean, organise, and work with huge amounts of data. It is a basic, everyday job of a data scientist. 

• Basic machine learning – Machine learning is one of the most important subjects to learn as a data scientist. You must understand how prediction models work. It is an important next step after you are done with your programming and statistics basics. 
• Data visualisation – Being a data scientist, you will be required to present your analysis to the brand heads, managers, or even department heads. You should know how to present data clearly through charts and graphs to help others understand your discoveries quickly. 

You do not need to master everything at a single time. You can create these skills slowly and gradually, along with continuing your degree. This plan works well for most of the students. 

Step 4: Earn a valid and useful certification

Along with a degree, an online upskilling certificate is important too. There are multiple trusted platforms that offer beginner-to-advanced courses in subjects like programming, statistics, and machine learning, which can help you apply classroom learning to real-world and practical problems.

The following are the reasons why certifications are important: 

• To fill any empty gaps that are left by your degree programme
• To learn particular tools that are used in the industry
• To show employers that you are active and passionate about constant learning
• Create a better and more complete skill set before you start applying for jobs. 

Along with all the reasons that show why certifications are important, it is also important to know that they generally work best as a support. To enjoy their complete benefits, you should have at least a bachelor's degree. They are not a replacement for a full degree, specifically for those students who are planning a long-term career in data science. 

Step 5: Start building real-life and practical projects

This is the step that is usually the most important part of understanding how to become a data scientist after 12th, but still it is skipped by the majority of students. Creating or building new projects is important, as they show that you have the capability to apply your learnings to real-life business problems. 

The following are some of the good project ideas for beginners: 

• Analysing a public dataset to spot patterns or trends. 
• Creating an easy prediction model, such as predicting sales or exam scores
• Building a data visualisation dashboard for any that seem interesting to you
• Studying or analysing consumer behaviour with the help of sample business data

Step 6: Earn experience in internships

Internships act as an important bridge between academics and full-time employment. Various companies actively look for interns who are willing to work passionately for them. They even offer internships to students who are still completing their degree to give them a fair chance to work on a real and practical business problem. 

The following are the benefits of having experiences in internships:

• It helps you figure out the real-life work scenario of a data scientist in a corporate setting. 
• It gives you a subtle confidence in your technical skills and how you use them.
• It helps you make better and more professional connections with people around you, so that it can help you in further job hunting. 
• It gives strength and attraction to your resume by simply adding a practical and real-world experience section below. 

Step 7: Go for beginner-level jobs initially

Now, imagine you have a degree in your hand along with the basic technical skills, a few real-life strong projects, and appropriate internship experiences. Do you think you are ready to apply for a senior-level or experienced-level job? No, right? This is why you should start your journey by applying for beginner-level jobs, instead of directly going for high-end jobs. You can start with job roles like data analyst or junior data scientist before shifting into advanced and expert-level roles. 

The following are some of the important points to focus on during the job hunting phase: 

• You do not have to stick to a beginner-level job, which is why focus on building an organised resume that can highlight your skills and projects and increase your chances for high-end jobs. 
• Experience is the most important thing to gain from beginner jobs. You must notice and practise common and popular interview questions that revolve around statistics, coding, and problem-solving.  
• The only way to let employers know about your capabilities is by telling them about it. This is why another thing to learn is to clearly explain your skills and project work in the interviews. 
• Lastly, you must always keep learning. Big companies will have different and advanced tools along with a lot more data than what you practised with while studying. You should always be open to learning new skills and techniques for working with data. 

Where can you learn data science on the internet? 

You completely understand the importance of side skills along with the main degree. There are multiple kinds of platforms online that offer skill learning at your own pace. 

The following are some of their examples sorted into categories for you:

• Well-organised online courses – The Internet is the hub of hundreds of reliable platforms that offer strategic courses in Python, statistics, and machine learning for beginners as well as experts. They are created by institutions and industry experts. 
• Unpaid learning platforms – Investing a certain amount of money beforehand is risky, right? You can choose from multiple unpaid websites offering free lessons in mathematics, programming, and logical thinking. They help you build your core skills for free, along with making things clear if you want to learn these skills at an advanced level by paying for them. 
• YouTube tutorial videos: Many experienced professionals decide to step up on social media platforms like YouTube and share all the skills that they have learned and earned. Many of them even share step-by-step coding and data project tutorials that specifically help visual learners. 

• Published guides and documentation: In the IT field, everything is noted down. Programming languages and tools also usually have published and official guides that give you clarity and accuracy on the concept.  

Conclusion

The first simple truth for learning how to become a data scientist after 12 is this: It is a career that is not built overnight but step by step. Preparing for this field is very important while selecting the right subjects in school, selecting the right bachelor’s degree, gaining core technical skills, and building real projects.

A full data science role is generally a few years after 12th, but once you know what to focus on at each stage, the path becomes a lot clearer. With consistent efforts, the right choice of subjects, and continuous hands-on practice, students who start right after 12th can make a good, well-prepared road to a rewarding career in data science.

“Remember, it’s not a straight-line journey. Some students need longer to develop good programming skills. Some people learn statistics faster, but they are slower to learn coding. That is quite normal. " Incremental progress and willingness to learn, and a real interest in using data to solve real problems, are what matter. Keep those three things in mind, and the rest of the journey tends to fall into place over time, one skill and one project at a time.
