    Every year, American high school students take SATs, which are standardized tests intended to measure literacy, numeracy, and writing skills. There are three sections - reading, math, and writing, each with a maximum score of 800 points. These tests are extremely important for students and colleges, as they play a pivotal role in the admissions process.

    Analyzing the performance of schools is important for a variety of stakeholders, including policy and education professionals, researchers, government, and even parents considering which school their children should attend.

    You have been provided with a dataset called schools.csv, which is previewed below.

    You have been tasked with answering three key questions about New York City (NYC) public school SAT performance.

    # Re-run this cell 
    import pandas as pd
    # Read in the data
    schools = pd.read_csv("schools.csv")
    # Preview the data
    # Which schools are best for math?
    best_math_schools = schools[schools["average_math"] >= 640][["school_name", "average_math"]].sort_values("average_math", ascending=False)
    # Calculate total_SAT per school
    schools["total_SAT"] = schools["average_math"] + schools["average_reading"] + schools["average_writing"]
    # Who are the top 10 performing schools?
    top_10_schools = schools.sort_values("total_SAT", ascending=False)[["school_name", "total_SAT"]].head(10)
    # Which NYC borough has the highest standard deviation for total_SAT?
    boroughs = schools.groupby("borough")["total_SAT"].agg(["count", "mean", "std"]).round(2)
    # Filter for max std and make borough a column
    largest_std_dev = boroughs[boroughs["std"] == boroughs["std"].max()]
    # Rename the columns for clarity
    largest_std_dev = largest_std_dev.rename(columns={"count": "num_schools", "mean": "average_SAT", "std": "std_SAT"})
    # Optional: Move borough from index to column
