Education

Grading schemes are local and rarely written down clearly, so each tool here shows the scale it is applying and lets you change it. The funding tools sit next to the investment ones deliberately: paying for education is a financing decision before it is an academic one.

Grading

CGPA to Percentage CalculatorCGPA to percentage across the four rules in common use. They disagree by several points on the same CGPA, so the rule your institution specifies is the answer and the others are not.Percentage to CGPA CalculatorPercentage back to CGPA. The conversion is only reliable in reverse if you use the same rule that produced the percentage, and applying a different one produces a figure that will not match the transcript.SGPA to CGPA CalculatorCGPA from semester SGPAs, weighted by credits. Averaging the SGPAs equally is only correct when every semester carries the same credit load, which is rarely true.Attendance Percentage CalculatorAttendance against a requirement, and exactly how many more classes you can miss. The useful answer is not the current percentage, it is the number of misses left.Class Rank and Percentile CalculatorYour percentile in a set of scores. A percentile is the share of people you beat, not the percentage you scored, and the two are constantly confused.

Exams

JEE Percentile to Rank EstimatorRank estimated from a percentile. At the top of a million-candidate exam a hundredth of a percentile point is a hundred ranks, which is why percentiles are quoted to four decimal places.

Productivity

Reading Time and WPM CalculatorReading time from a word count, adjusted for how dense the material is. Silent reading runs around 238 words a minute; reading aloud is closer to 130, which is why the two answers differ so much.Typing Speed (WPM) CalculatorTyping speed on the standard convention where a word is five characters, with errors deducted. Net speed is the only figure worth quoting, since gross speed rewards typing fast and badly.
