What to do when completing a full-time masters by research, and a part-time job interferes with grades and progress? I'm currently in first year of MS by Research in computer science. The first year includes coursework and second year is research thesis.
I've been working part time 20 hours a week in a software company. I have 4 subjects. So far I have managed to complete assignments but haven't really studied well.
Now as the semester is close to end, I have projects, assignments and exams. I'm struggling to decide if I should continue working here. Sometimes I think it's doable but it's a little risky. I may not get proper marks to progress to next semester. What would you do in such situation?
It is most certainly possible to get a research degree while working part-time --- or even full-time.  I know a number of people who have done it.  As you are finding, it is quite rigorous, however.  In many cases, it may be better to take the coursework part time, so that you have enough space to really absorb the material, rather than just trying to hit passing marks.
