Monitoring progress every week and making changes to the learning plan

What is Data Science?

Let's first see what data science is before jumping into timelines.

Data science is a cross-disciplinary approach that employs scientific methods, algorithms, statistics, machine learning, and domain expertise to derive insights from structured and unstructured data. A data scientist employs programming languages like Python, R, SQL, Excel, Tableau, and cloud-based platforms to collect, process, analyze, and visualize data.

Core Areas in Data Science:

• Data Collection and Cleaning
• Exploratory Data Analysis (EDA)
• Statistical Modeling
• Machine Learning
• Data Visualization
• Deployment and Productization

Who Can Master Data Science in 6 Months?

You do not have to be a math whiz or a computer science graduate. You just require a learning aptitude and a minimal familiarity with computers.

Ideal Candidates Are:

• Engineering graduates (CSE, ECE, Mechanical, Civil, etc.)
• Working professionals from software development, testing, digital marketing, etc.
• Graduates from non-CS streams (commerce, arts, bioinformatics)
• Anyone seeking a career transition into data or AI-related fields

Best Practices for Learning Data Science in 6 Months

To be successful within this six-month mission, you require structure, discipline, and the correct strategy.

Tips that Work:

• Adopt a daily learning routine and adhere to it
• Learn concepts prior to tools
• Practice on a regular basis—don't merely read or watch videos
• Regularly work on mini-projects to solidify learning
• Participate in online forums and discuss issues
• Monitor your progress with planners or checklists
• Develop a portfolio of actual projects

Learning Platforms and Tools That You Should Familiarize Yourself With

The following are tools and platforms that will hasten your learning:

• Languages: Python, R
• Libraries: Pandas, NumPy, Scikit-learn, Matplotlib, Seaborn
• Databases: SQL, PostgreSQL, SQLite
