Hey, a private job can be tough for many. I also faced the same problem during my job. That's why I moved toward the govt. job sector. In your case, I will suggest you go for the IIT JAM exam, as this is the only way you can use. The IIT JAM exam is for those who have completed their B.Sc. degree and are willing to pursue a Masters in Science from IITs and IISc.

Hope this would help..!!
All the best..!!
