You asked on another thread about your chances for MIT.
I think the multiple Bs in STEM would make MIT a very long shot. (Although I don’t know about the rigor at your high school. Maybe you attend a high school with severe grade deflation?)
Of course if you don’t apply, the chance is zero, and applying would increase your chances. 
If MIT truly inspires you, I think it can be a good experience to put together its application, even though it is somewhat long and complicated. My daughter applied EA, and she told me that writing the MIT essays and putting together her portfolio was a valuable experience for her, during which she learned more about herself.
She also thought there was a fair bit of overlap between the MIT essays and the UC PIQs, so she felt that it helped her write better PIQs also.
Would you like some help with the “likely” and “target” parts of your college list? That part of your list is important too!
