Hello,

This is my first time of posting here. I'm interested in PhD program in US and plan to write my GRE/TOEFL by July or August for the Spring/Fall admission circle.
Below is my brief profile:

BSc Industrial Physics - 4.07/5.00
MSc Geophysics - 4.0/5.0
HND Mech Eng - 3.63/4.00
ND Mech Eng - 3.68/4.00
Currently, I work as an assistant Lecturer in a University here in Naija.

Programs of interest:
PhD Physics (Soft Matter or Nuclear)
PhD Nuclear Engineering
PhD Mechanical Engineering

Here are my grey area of concern:
1. Is there need for me to write another GRE Physics subject after writing the GRE General paper?
2. Do I need to convert my transcripts to WES?
3. What option(s) (Physics or Engineering) is best for me at this point for easier admission? I'm interested in both disciplines; so anyone can serve base on advice.
4. If there's any possible GRE prep group I can possibly join, please kindly add me to it to ease my preparation.
5. Do I need to apply for another Masters or straight PhD if I choose the Engineering field?
5. My email - comrade.dpsi@gmail.com

Thank you very much as you advise appropriately.
