- What is the undergrad course workload difficulty among these majors, so that he can get time to do research/volunteer/shadowing
All three majors will have required laboratory classes and require an equivalent amount time.
Chemistry is more math-intensive than the other two majors and may require Calc 3 and diff eq for majors
Do any of these majors have an advantage over other in preparation for MCAT? I read somewhere that 70% of MCAT is chemistry based
Chemistry and physics together make up 1/4 of the MCAT. Biology and biochem is another 1/4. Soc, psych and human behavior is another 1/4. The last 1/4 is analysis and critical reasoning.
Additionally beside the MCAT, most med schools (and some medical residencies) now require students to take situational judgement exam. A class in medical ethics is helpful for SJTs.
If he takes Chemistry and goes into Med school, would he be able to catchup on the Biology coursework in med school?
It helps a little bit if a student has seen the material before, but it’s not critical. Med school is extremely fast paced. An entire semester’s worth of material from, say, an undergrad class in genetics or immunology is covered in 2 or 3 lectures (or about 1-1.5 weeks) in med school.
Would a research in Biology lab have an advantage over other labs for med schools
The purpose of research experience in undergrad is not to teach specific lab techniques, but to learn about and understand the research process: how to do a literature review, how to develop a thesis, how to design a testing process, how to collect data, how to do data analysis, how to formulate conclusions, and how to understand the strengths and shortcomings of your experimental design/results.
My older D did research in medium energy particle physics in undergrad. She learned about the research process. (But not a single med school interviewer asked about her research, probably because they simply weren’t familiar with the field. It was different story with my younger D who did neuro/psychiatric research in brain cognition and later brainsimaging studies about addiction. She fielded a lot of questions about her work.)
Research is not the most important element in developing a strong med school application.
That said, if your child is looking to get involved in specific research fields or if they want to aim for certain specialties where research & publication is a expectation in applicants, then prior bio lab research may be useful.
How is the curriculum for Neuroscience? Is it heavy on psychology?
School/program dependent. My D was a neuroscience major and at her university, she took zero psychology classes for her major. It was all bio and cognitive science. Other programs are psychology heavy and lighter in the biology.
What if he changes his mind during undergrad, which major would lead him to good job prospects after undergrad?
Generally speaking undergrad bio degrees don’t have the best post -graduation employment options. Having said that, a plain vanilla bio degree is more employable than specialized bio degrees (including neuroscience). There are things a bio or neuroscience student can do to improve their employment options-- taking some extra higher level math classes (particularly in statistics and probability), learning coding skills (R, Python, MatLab), basic computer programming and doing industry internships during summers in college. Biotech firms will hire bio bachelor’s if they have the right mix of skills.
Generally speaking, chemistry is the most employable of the three, but jobs will likely be in an industrial setting–think QA labs in pharmaceutical, agriculture, energy/petroleum, food production, etc, and
