Preferably with low tuition fees
Open to travel anywhere in America
Looking for a program in the engineering side, not medical
MITES application is due on Feb 1st, so that's coming up soon. I would look at TASP, RSI, and SSP. There are tons of articles on this, but this one I find to be the best - https://www.shemmassianconsulting.com/blog/summer-programs-for-high-school-students
TASP, It is free and very prestigious. It offers academic challenges that you don't encounter in high school. Applications are due around November.

Where do you live? Are you willing to travel? If you edit your post to include a bit more information it will probably help you get some more detailed responses. Do you have an idea of what you want to major in too?
