Science Stream (PCM):

• Physics (P): Essential for computer engineering and data analysis.
• Chemistry (C): While not directly related to data analysis, it can develop strong analytical thinking skills.
• Mathematics (M): Crucial for computer engineering, data analysis, and the logical thinking required in business.

Commerce Stream (MEC):

• Mathematics (M): As mentioned above, important for various aspects of your goals.
• Economics (E): Provides a foundation for understanding business principles and markets.
• Computer Science (CS): Introduces you to programming and computational thinking, valuable for both computer engineering and data analysis.

Benefits of Each Stream:

• Science Stream (PCM): Provides a strong foundation in core sciences and mathematics, which is crucial for computer engineering and data analysis.
• Commerce Stream (MEC): Equips you with business knowledge and introduces computer science, potentially sparking further interest in these fields.

Additional Considerations:

• Creative Writing: While not a formal subject in Class 11 and 12, you can pursue creative writing independently through online courses, workshops, or personal projects.
• Psychology: Similar to creative writing, consider online resources or introductory psychology courses offered by some institutions to explore this field further.

Beyond Class 11 and 12:

• Bachelor's Degree: Choose a program that aligns with your dominant interests - computer engineering, business, data science, or a combination (e.g., B.Tech. in Computer Science and Business Analytics).
• Online Courses: Take advantage of online courses in creative writing, psychology, or other areas of interest to continue exploring them alongside your main field of study.
