# Calculate an average with scores and grades

### What can be 'averaged' in iDoceo?

Short answer: Anything, any column with any kind of content. Even icons.

Elaborated: Each column in your grade book has a 'Grade type' or 'Grading scale' asigned. This allows iDoceo to combine different kind of columns and grade scales in a single calculation and represent it in a 'Calculation' column which in turn has a grade scale or type assigned as well.
This basically means that you can mix any kind of columns in the average and the result can be represented as a grade, percent, or any other grade type , even your own.

You can add as many calculations as you need to in the grade book, linking a result with another calculation, or mixing columns from different tabs (details here).

#### A brief introduction

In this article, we will explain different kinds of calculations and its results with different grade types. In essence all boils down to the same steps:

- Add a column > Calculation > Weighted average
- Select the columns that you'd like to take into account (by tapping on its headers)
- Choose the Grade type that will represent the Result (i.e. A to F, or 0 to 100 for a percent)
- (optional) Assign the weight on each column. By default it calculates same weight for all columns.

### A Custom Weighted average

!-

In this example we are calculating the average of Test 1, Test 2 and Test 3 .
The grade type on all four columns (including the calculation) is set to generic with Total points = 100.

As soon as you configure a column with a different grade type, you will need to set a grade type to the rest of columns involved in that calculation. You can mix any kind of grade types: numeric,text or grade conversions

--> After adding the average calculation, you will have to tap on the headers of the columns you would like to take into account to obtain the result Here is the final result Simple averages,Total points grading and Categories are straight forward with folder's configurations

#### Simple Average

- Add a Category / Folder . Tap on the plus sign on the right top of the gradebook
- Choose the Grade type Result and the Calculation desired (i.e. 0 to 100 and Weighted Average - Add as many columns as needed inside the folder, by tapping on the folder's Three points and after that, tap on Add Column .

Columns can only be added while the folder is open, in case it is closed, tap on the folder icon to open it - Its done ! You can start filling the cells with the exam's grades, The main folder's column will show the average result without further configurations. ### Representing the result as a text grade

In our previous example, the calculation's grade type was set as generic Max points = 100. To show the result as a grade from A to F just change the Grade type result to "Text grades A to F".
