Yes, your daughter can certainly pursue a Bachelor of Business Administration (BBA) after completing her 12th grade with a Biology and Computer Science background. BBA is a versatile course that does not require a specific stream in 12th grade, making it accessible to students from Science, Commerce, or Arts backgrounds.

### Key Points to Consider:

1. **Eligibility:** Most universities and colleges require a minimum percentage in 12th grade, usually around 50-60%, but this can vary depending on the institution. Since your daughter has studied Computer Science and Biology, she is eligible to apply for BBA programs.

2. **Entrance Exams:** Some reputed institutions might require your daughter to appear for entrance exams such as IPMAT (for IIM Indore), DU JAT (for Delhi University), or other college-specific entrance tests. These exams typically assess aptitude in areas like quantitative ability, logical reasoning, and English.

3. **Advantages of Science Background:** Her background in Computer Science could be beneficial, especially in today’s digital-driven business environment. This knowledge might give her an edge in subjects like Business Analytics or Information Systems, which are increasingly integral to BBA programs.

4. **Career Prospects:** BBA offers a strong foundation for careers in management, finance, marketing, human resources, and more. It also serves as a stepping stone for further studies like an MBA.

In conclusion, your daughter is well-positioned to pursue a BBA, and her diverse academic background could even enhance her adaptability and performance in the program.
