With a related field's completion of a diploma, you can get admission into the Bachelor's program. Many universities allow lateral entry into the second year of the degree for those with a diploma, which implies you are not required to take the first year. This pathway lets you dive further into the details of concepts in electrical engineering and gain more specializations.
Some courses may have prerequisites, like GPA or a list of required coursework. You may then proceed with higher studies: Master's in Electrical Engineering or even a Ph.D., which again branches off into lots of different opportunities within power systems, telecommunications, electronics, and control systems areas, just to name a few. There are also opportunities to specialize in the newer areas of electrical engineering, like renewable energy or robotics or artificial intelligence
