How early must one focus on engineering in college?

<p>I did consider Lehigh but I am not 100% sure if I want to apply there. Nonetheless at this point I don’t really want to choose a university based on the quality of the engineering program. However they did give me a reasonable number on the NPC, and most of the schools I have a decent chance of getting into aren’t giving sufficient $. All of the Unis on my list are affordable based on NPC except Tulane, but the application was free so I decided to fire the trigger and maybe get some merit. Prob won’t be affordable anyway though, but that’s ok.</p>

<p>Is it even worth my time to apply to those three? Are the chances so infinitesimally slim that it would be a waste of $$ to apply? The less-than-ideal class rank is due to me not taking challenging courses my freshman and sophomore year, although it is somewhat disheartening to see that something like 90% of the kids accepted to these schools were in the top 10% of their class.</p>

<p>If it helps at all, I have a somewhat “special” family circumstance - I live in a single parent household and my mom works nights every weekend and a day or two in the week, and I have to stay home and watch my brother. I also do a part-time job.</p>
