Eligibility Criteria for Data Science Courses After 12th

The data science course eligibility is usually simple, and it varies by course type and college.

Basic eligibility for data science after 12th:

  • Minimum qualification: 12th pass (any recognized board)
  • Typical marks: Many colleges ask around 45%–60%, depending on institute
  • Maths matters: A strong base in Maths helps a lot, but not every pathway requires PCM

Stream-Wise Clarity:

PCM (Physics, Chemistry, Maths)

  • Required for most B.Tech Data Science programs
  • Helpful for a strong mathematical foundation

Commerce

  • Eligible for B.Sc or BCA Data Science (college-dependent)
  • Suitable for the business analytics pathway

Arts

  • Eligible in some programs
  • Must learn maths and statistics from the basics

Mathematics is important in data science-but students from non-maths backgrounds can build foundational skills gradually.

Types of Data Science Courses After 12th

Different students need different pathways. Choose based on time, budget, and how deep you want to go.

Degree Courses (Undergraduate)

Undergraduate data science courses are the most common option after 12th. They build long-term career depth and stronger placements.

Main degree choices:

B.Sc Data Science (3 years): 

Data-focused, balanced mix of statistics + programming + analytics.

B.Tech Data Science (4 years): 

Engineering-heavy with deeper computing, often through B.Tech CSE (Data Science specialization) too.

BCA Data Science (3 years): 

Software + data path; good for students who want coding plus analytics.

Difference you should know:

  • A B.Tech Data Science route is usually more technical and engineering-oriented.
  • A data science degree after 12th like B.Sc is more data-centric and analytical.

If you’re unsure, pick the path that matches your comfort with Maths and coding.

Diploma Courses

A diploma in data science after 12th is a shorter, skill-oriented option. It suits students who want faster entry into internships or support roles.

Why students choose a data science diploma:

  • Shorter duration
  • Practical tool learning (Excel, SQL, Python basics, dashboards)
  • Useful as a bridge before a full degree

These short duration programs work best when combined with projects and internship exposure.

Certification & Short-Term Courses

Data science certification courses are designed for quick skill-building. They’re ideal if you want to explore the field before committing to a full degree.

A beginner data science certification typically covers:

  • Python basics
  • Statistics fundamentals
  • Data visualization (Power BI/Tableau)
  • Intro to machine learning

Short term data science courses are great for building a portfolio, but they work best when you practice regularly and build real projects.

Data Science Course Duration After 12th

The data science course duration depends on the course type and learning depth.

Duration of data science after 12th (typical):

  • UG Degree (BSc/BCA): 3 years
  • UG Degree (BTech): 4 years
  • Diploma: 1–2 years
  • Certifications: 3–12 months

Why duration matters: A longer course timeline usually gives more time for fundamentals, projects, internships, and specialization - this often improves job readiness.

Short programs can still work, but only if you practice consistently and build proof of skills.
