To be an elitist prick, there are a lot of people that want to be engineers but the number who end up seeing it through to the end are often 20-30% of the initial people who try. It isn't so much wanting to play math tricks as it is grinding and plodding through turgid theoretical concepts with often crippling workloads that have the worst timing ever with your other classes. Not to worry as homework is only 5% of the overall grade but a two hour exam is worth 40%. If you can't understand shit on that major exam, not to worry as the average score is 45/100 so you probably end up with a B.
All to wind up using less than 5 percent of those concepts at your job. Also, there's no guaranteed job or guaranteed well paying job at the end. There are plenty of engineering jobs that get outsourced, engineers having to work as technicians, or hell, engineers getting laid off en masse because their consulting firm has hit a slump.
Basically what I'm getting at is that it is best to pursue your passions, even if it only pays $30,000 a year. Money isn't everything.
