AbhishekMali21/STUDENT-GRADE-ANALYSIS-PREDICTION ? reverse-engineered prompt

Build me a student grade analysis and prediction notebook that uses the Portuguese student dataset to explore what affects final exam performance and to predict whether a student will do well in the final grade.

I want it to load the provided CSV, clean and prepare the data, do some simple exploratory analysis, and then train a few different classification models to compare how well they work. Please include clear visualizations, basic feature analysis, and a final section that shows which model performs best with easy to understand results. If it makes sense, also turn the final grade into a simple good or not good outcome so the prediction is more practical.

Keep it beginner friendly, with readable notebook steps and short explanations of what each part is doing. Use the dataset in the repo, and if you need to look up current library usage or best practices online, go ahead.
