I have a strong interest in theoretical physics, especially mathematical physics, and pure math as well. by the end of four years of mechE i will have done calc 1,2,3, diff. eqs, numerical analysis. thts all the math we will be doing. now i was wondering if it would be possible for me to go to grad school in either of those fields.please tell me my options. like if i take some upper-level math courses at some uni and then apply?? or get a gud grade in gre of either of those two subjects?? or do u think it would still be impossible. ne and all help is appreciated.
