1. Is there any advantage of having 1.5 yrs of exp ? or should i have more? (Somebody told me that if anyone has more than 2yrs of exp he'll get some additional scores).
That is not true. There are no such standard criteria. Moreover, if you apply now, you will be working for over 2.5 years by the time you get an admit. These are the kinds of myths that you don't want to entertain. So, any work experience for any length of time will add to your strengths.
2. How difficult is the process from- getting the GRE score to- start going to college. Is it possible for a person who's employed to handle the situations without help of any external agencies, like coaching center's ?
YES! It most definitely is possible. However, you will need to approach the application process in a timely, professional manner and work out a detailed plan of action. Do be prepared to take a total of 1 - 2 weeks off over the course of a few months to take care of GRE preparation, the actual tests, obtaining reference letters, transcripts etc. Moreover, there are no high quality coaching centers and training programs that can actually do this for you in a professional way.
1. If I am working, or about to start work before applying, what is an ideal time to take the TOEFL exam?
A gre score is valid for 5 years and toefl score for 2 years. I suppose most people take up gre/toefl in the final year. If some of you are planning to work for more than a year, you should retake toefl.
Its better to take toefl as close as possible to the admission year.
