It’s almost a month now since the release f GeoGebra 4.2 and since then I have updated tutorials to the said version. The update to version 4.2 of the GeoGebra Essentials Series and the GeoGebra Basic Geometric Construction Series are now complete.

I will be updating the GeoGebra Intermediate Tutorial Series and the GeoGebra Advanced Series after Christmas. Hopefully, I will be able to finish them before new year.

For now, let’s enjoy the holidays with our families.  Have a blessed Christmas and a prosperous New Year to all.
