Now, please do not issue sarcastic remarks. Its a matter of serious career choice for me. Now with a 90 credit hour BBA with 3.6 CGPA is it possible to acruire the required courses through online or distance study?
(1) Most schools do not accept online courses period. University of California med schools DO NOT.
(2) PhD programs require previous research experience, and taking the GRE and/or that TOEFL for the english language requirement. Have you done this? Both require scoring well to get into.
(3) Both PhD and MD/PhD require PROOF of research experience, whether through letters of recommendation or publications. Do you have this?
(4) PhD programs require a sponsoring professor, therefore you may need to have a professor that is willing to sponsor you in addition to being accepted into the program.
(5) Pakistani (or most other places in the world) courses do not equal courses taken in the United States. You will have to take classes in the US. NOT ONLINE assuming you are trying to apply to a US med school. Many classes have labs, such as organic chemistry, general chemistry and biology. How can you do those online?
and the most important question of all.
(6) How are you going to gain entrance into the United States or US territory (Caribbean) and become a permanent resident to just take classes?
I don't think you have a grasp of your situation or reality at this time since you are now asking about getting into an MD/PhD program without any documented research experience, let alone the classes needed to get into either MD or PhD program. I wish you luck but I don't think luck will help you unless you actually figure out a REALISTIC goal. Sorry to be blunt, but I'm sure everyone can agree that you have exhausted what can be said on SDN to "help" you.
