📌 Important Notes

• Total Marks: 100 (15 marks GA + 85 marks core subjects) (GeeksforGeeks)

• The core syllabus covers foundational undergraduate CSE topics and expects both conceptual understanding and problem-solving skills.

• No physical calculator is allowed in the exam; a virtual scientific calculator is provided.
