Welcome, two years at your age and level of progress is nothing. Just bite the bullet, do some thorough research in the best college to attend and just do it. Choose a path to follow and follow it through with zeal. When that doctrine is complete then choose other attributes to add to your resume and skill-set.
I am surprised you signed up for a college/school that you did not investigate at all prior to signing. Engineers are careful and studious people, we have to be or structures fail and people may die.
If Engineering is to be your career then now is the time to start taking things on real values (research first) rather than just face value, hoping something is right, or just luck.
