DSCS-102 Guess Papers & Solved PYQs: Your Strategic Edge for YCMOU’s Data Science Term-End Exam

YCMOU’s DSCS-102: Data Science Fundamentals demands rigorous preparation for the 80% weightage Term-End Exam (TEE). This resource eliminates guesswork by providing exact Solved Previous Year Questions (PYQs) from 2020–2025, curated to match the 2025 Pattern syllabus and Continuous Assessment (CA) question patterns. Unlike generic study guides, these papers include faculty-verified model answers with step-by-step derivations for Algorithms & Data Structures (Unit 3) and Statistical Computing (Unit 5)—two high-scoring TEE chapters.

Academic Objectives Aligned with YCMOU’s DSCS-102 Curriculum

This guide targets core learning outcomes for B.Sc. Data Science (Semester 1), including:

• Unit 1: Introduction to Data Science – PYQs on Big Data frameworks (Hadoop/Spark) with YCMOU’s official case studies from Maharashtra’s healthcare analytics projects.
• Unit 2: Data Wrangling – 15+ solved problems on SQL joins and Pandas operations, formatted per YCMOU’s Home Assignment (गृहपाठ) guidelines.
• Unit 4: Machine Learning Basics – Regression & Classification questions with Python code snippets (using Scikit-learn) annotated for clarity.

Continuous Assessment (CA) & TEE Preparation: A Dual-Focus Resource

Students often struggle to correlate CA Home Assignments with TEE expectations. This guide bridges that gap with:

• CA-ready questions marked with ★ symbols, identical to YCMOU’s Study Centre model answers for Unit 6: Data Visualization (Matplotlib/Seaborn).
• TEE-specific guess papers highlighting 80% recurring topics (e.g., K-means clustering in Unit 3) from 2020–2025 TEE papers.
• PRN-compatible solutions for Self-Instructional Material (SIM) gaps, with cross-referenced page numbers to YCMOU’s official textbooks.

   • Use Solved PYQs to identify weak areas in statistical tests (Unit 4).
2. Phase 2: TEE Focus (Weeks 7–10)
   • Prioritize guess papers for Units 3 & 5 (highest TEE weightage).
   • Replicate YCMOU’s exam format with timed practice using provided answer keys.
3. Phase 3: Revision (Final Week)
   • Focus on 10 most frequent TEE questions (highlighted in red).
   • Cross-check PRN solutions with SIM Chapter 7 for Data Ethics case studies.
