After deciding which engineering field you are interested in, it is a good idea to visit schools that have that program. Every college has its own personality and all schools do not follow the same programs of instruction. This is something every student needs to consider when deciding if that school is the one for them. When you go on some college tours, you will start to see what aspects of schools you like, or do not like. This is the best way to start narrowing down choices of schools. By going on different campuses you will get a feel of what each school is like. The size and look of the campus, what the facilities and classrooms are like, and what the class sizes are will give you an indication of what is best for you. Try to take the engineering school tour at each school, if possible. An engineering tour will give more insight into what the curriculum is like and what life as a student in their program will be like. In addition, talking to current students and speaking to administrators about the specifics of the program you are interested in will give you more information. The administrators can also provide more specifics on the requirements for admittance to their program.
If you are not sure where to begin, first start exploring colleges that may be a short distance from where you live. This is a great way to start narrowing down what type of schools you are interested in without spending a lot of time and money.
