GRE

Hi Sairohith,
A GRE score of 310 to 315 would be pretty acceptable with TOEFL 115 onwards.

Hi Ayusha,
Yes, you can take GRE to start with your admission process.

You can target top universities like NUS Singapore, Carnegie Mellon University USA, Indiana University Bloomington, Cornell University to name a few. Universities in USA have an holistic approach towards admission so even if your UG grades were not too high you do stand a chance. A very good SOP and Letter of Recommendations will be crucial. Additionally, extra curricular activities, achievements, work experience, internships, projects etc. will also be evaluated. The final decision will depend on the university.

Hi Akarsh,
They do not require a GRE score. University of Toronto offers a M.Eng and MAsc in civil engineering. Both the programs have different requirements. I will therefore urge you to check their website and see which program you would fit into.

GRE boosts your application. You can check the university requirements.

Hi
In order to get admission in good MBA programs in the US it is important to have GMAT/GRE taken with good scores.

Graduate Record Examination (GRE) is a standardized test is an admissions requirement for most Graduate Schools in the United States. Exam aims to measure verbal reasoning, quantitative reasoning, analytical writing and critical thinking skills that are not entirely based on any specific field of study outside of the GRE itself. The GRE General Test is offered as a computer-based exam administered at Pro metric testing centers.

Yes, you can.
GRE scores are valid for five years, so apply for the foreign universities before the score expires or you can retake the exam.

You need to appear only in GRE and IELTS for the same.
