Earlier in the year, I applied to some graduate school master's programme in the US and have received a few offers last week.
My goal is to obtain a PhD. Ultimately, I have two options.
Take the graduate school offer. It is a top 15 programme for mathematics and after completing 1~2 years there, reapply for PhD programmes probably in the US or other places.
Try to wait two years when I qualify as a teacher. Work with a local professor to try and reapply again.
Bit of Background: I spent many years outside of my country during secondary education and also during my undergraduate. After graduation, I had worked as a teacher to try and get my diploma to be a fully-certified teacher. Note, I worked in a country which is not my home country so to speak but I have relatives there and many family connections. This year was supposed to be my contract renewal year and after failing to get into a teacher training programme in the first two years of my teaching job, I had planned on other pathways which was to get back into academia. I had intentions of doing a master's and had made applications before to my home country and UK which is where I did my undergraduate. On those occasions, it didn't work out.
This time round, I applied to a dozen schools in the US with a good score in my subject GRE. As mentioned before, the school that I am considering is a top 15 school.
Personally, I want to take option 1, go to the graduate school programme and reapply for PhD but if I quit my job, I have no back-up options should I not be able to complete my master's or PhD. This is a real concern as I have been out of academic studies for three years and despite trying to do some mathematics when I have the time, there is no denying that I will be rusty.
The second option is to wait for two years. If I fully qualify as a teacher, I can always return back should I have to quit. I personally feel that five years out of academic study is quite long but this is something that some people have suggested. Is returning to academic studies really possible after such a long break?
TLDR: Got into a decent master's programme, want to accept it but worried about back-up options since I have been out of study for so long. Can I wait two more years to consolidate a back-up plan in teaching and try to re-enter?
