Chemists/Physicists: Is it advisable to take 3rd Bachelors program: BS Mathematics after first Double Major? Well, my reason is that I ended up hating biotechnology (biochem in particular) and I'd like to see myself doing quantum chemistry (I'm a 5th year student of a Bachelor's program in Biotech and Chemistry). Can I take a mathematics degree while working? Im not quite familiar with the work of Chemists field/lab because i've not yet enrolled my On the job training course, so my question is: can you squeeze working while studying math? I'm really quite confused because I finally found the field that I see myself in, however I know that I lack the knowledge in math to proceed to higher quantum chemistry. As a fifth year student, I cannot take electives or minors in mathematics.
