Hi Jel,
It might also help to just go through the basis/fundamental of GIS
which will help you in learning/understanding the software. Things
like the layer concept. Vector and Raster data models. Spatial objects
with tabular data, spatial reference systems/coordinate systems etc.
>From my experience. Spatial reference system is overlooked by many new
GIS people but the basis of GIS is really the spatial component. I
have seen people worked on and digitized on layers with different
spatial reference systems unknowingly and when they try to put them
together they get messed up. Luckily these days a lot of software do
on the fly projections but its still important to understand Spatial
reference systems or at least keep your data to a consistent spatial
reference system.
Going through the basics would also allow you see and do more with GIS
apart from just making static maps as you were looking at.
All the best with your en devours
