Data Interpretation (DI) in UGC NET Paper 1 is all about reading the graph correctly and doing quick calculations with confidence. In this Easy Level Line Chart set, you will mostly solve direct questions like totals, simple differences, basic averages, and one-step percentage change. If you practice daily one DI set per day (5 questions) for 10–15 minutes, your speed and accuracy will improve naturally, and you will feel more comfortable with graphs in the final exam.
