What technical level will you achieve?
Every step requires more time and effort, but the best engineers merit the best and most interesting jobs. Also consider that aiming for the top might not be the best use of your time. For example the course you need now might be a stepping stone to an advanced technology.
Assess your aspirations against the course and exam objectives as well as the estimated time to complete.
A detailed guide can be accessed from the Exam Prep Hub, laying out how to achieve a specific tech level of technical ability and passing the exam.
