First thing: register with Disability resources/disability services.
Bringing a laptop to bring to class won’t make you stand out at all - MANY students do that nowadays. But registering with Disability will give you the extra time
(Those kids who told you your grades didn’t count were cruel and, most importantly, wrong. Haven’t they ever heard of “levelling the playing field”? You’re fighting with disabilities, they’re not. You deserve accomodations otherwise they have an unfair advantage over you since they don’t have to fight OCD nor ADD.)
Second thing:
As a premed, you don’t have to major in biology; you can major in anything (and biostatistics or bioinformatics would have more professional outcomes than straight biology). Regardless, you’ll need to take these classes over the course of four years
1 semester each of calculus, statistics or biostatistics, psychology, sociology, biochemistry, a course that deals with diversity (+, if you can, neuroscience/cognitive science/neurobiology because so much is happening in the field right now, more in biostatistics, bioinformatics)
2 semesters each of biology, chemistry, organic chemistry, physics, English communication/writing/speech (+ if you can, speaking a language that is spoken by an immigrant group in the US with relevant experience at a clinic).
As a result, you don’t block any major by taking a regular “premed” schedule and deciding during sophomore year.
You could take:
Freshman year, Fall
Calculus
Biology1
English Composition
Sociology
Foreign language or art or other general education requirement
Freshman year, Spring
Biostatistics
Biology2
Chemistry1
English Communication
General Education requirement in arts or humanities
Freshman year, Summer (or Maymester)
Chemistry 2
Sophomore Year Fall
Physics1
Organic Chemistry1
Psychology
one major-related class
one easy class or nothing else
Sophomore Year Spring
Physics 2
Organic Chemistry 2
one major-related class
one easy diversity-related gen ed class
All universities would have these classes regardless of what major they offer (or don’t). It’d cover what you need for premed and doesn’t close any science major. Or you could even spread them out more.
