Please use the following equation if you have a foreign BSc. high score:
GR_TUM = 3 * [(GRmax - GRd) / (GRmax - GRmin)] + 1
GR_TUM = the GPA you're looking for, converted GPA (German/TUM system)
GRmax = highest possible grade in the non-German grading system, expressed in numbers
GRmin = lowest possible
passing grade in the non-German grading system (i.e. the lowest possible   grade that would still allow you to pass the course)
For the result in the application form, please just use one digit after the comma.

#### Special cases:

- If the system works with percentage, please just use the number without the % sign in the equation.
- If the system works with letters, please just convert the letters into numbers.
Example:
A = 5
B = 4
C = 3
D = 2
E = 1
F = 0 (fail)

GRmax = 5
GRmin = last grade to pass = 1

A+A+B+C = 5+5+4+3 = 17
GRd = 17:4 = 4,25

The resulting equation would be:
GR_TUM = 3 * [(5 - 4,25) / (5 - 1)] + 1 = 3 * 0,75/4 + 1 = 0,562 + 1 = 1,562
--> one digit after the comma --> your "new" GPA (to use in the application form) would be 1,5
Please keep in mind: The German system recognizes grades from 1,0 (best) to 4,0 (lowest possible passing grade) - so the result should be within this range.
