To answer your question, we'll break it down into two parts:

Reappearing for HSC Board Examinations in 2025

1. Eligibility: Check with your state's board of education (e.g., Maharashtra State Board) to see if you're eligible to reappear for the HSC board examinations in 2025.

2. Application process: If eligible, find out the application process, deadlines, and required documents.

3. Exam schedule: Verify the exam schedule for 2025 to ensure it doesn't clash with other important events, like BITSAT.

Giving BITSAT in 2025

1. Eligibility: Check the BITS Pilani website for BITSAT eligibility criteria, which typically includes passing the 12th standard examination.

2. Application process: If eligible, register for BITSAT 2025 within the specified timeframe.

3. Exam schedule: Note the BITSAT exam dates to plan accordingly.

Considering both, it's possible to reappear for HSC board examinations in 2025 and give BITSAT, provided you meet the eligibility criteria and manage your time effectively.

To confirm, I recommend:

1. Visiting the official websites of your state's board of education and BITS Pilani.

2. Contacting the authorities directly to clarify any doubts.

Stay organized, focused, and prepared for both challenges!
