Give you some model question papers in 4th sem cse?

I can't provide specific model question papers, but I can suggest typical topics that may be covered in a 4th semester Computer Science curriculum. You might encounter questions on data structures, algorithms, database management systems, software engineering principles, and computer networks. Additionally, practical exams may focus on programming assignments or projects related to these subjects. I recommend checking your university's resources or contacting your professors for past papers or sample questions.
