Canada

Some of the PG Diploma Courses, which you can go for in Canada are:
1. Conflict Analysis and Management
2. Disaster and Emergency Management
3. Educational Leadership and Management
4. Environmental Education and Communication
Though I will recommend you to go for a Master's Degree in a subject or course related to your graduation course. Some examples can be:
1. M.Sc. In Chemical Engineering
2. Master of Applied Science in Chemical Engineering and Applied Chemistry
3. M.Sc. In Chemical and Biological Engineering
4. M. Eng. In Chemical Engineering
So, first you should decide you want to continue in same course of study or not and then choose a course for your PG.

Hello Saurabh,
Yes, there are always chances of getting admission for MS in CS respective of your performance in your B.Tech. Foreign universities look for a different matrix of criteria to admit students. If you have done well after getting a job and has proof of this to show, along with different aspects of extra curricular activity or social service then it's a big advantage to you. However I will like to advise you to approach an agency which is dealing with sending students abroad for MS. This is because there are plenty of nuances which play critical roles and these agencies are aware of this role and take care of these nuances, and hence your chances of securing an admission improve drastically If you can get assistance from one such agency. Best wishes to you.

Hi Dhruvil, what is best for you, this is a common question asked by students, many times they forget they are the only one to know this answer. First of all ask yourself why you want to go to Canada, what are your career plans, do you like mechanical engineering, what specializations or subjects you enjoyed, any other likes and dislikes and so on. As a whole engineering has good scope in Canada so you can select wisely, depends on what you like. Automobiles, Design, Product management, Transport and Manufacturing, robotics, aerospace and so on. You can also study engineering management or management studies if you are interested towards business and management.
