When should I take the Graduate Record Examination and TOEFL?

First thing first, get over with your GRE as soon as possible. Because TOEFL is not big deal if you have attended English Medium school and college. Don't take too much time waiting for the "perfect preparation" . As there is flexibility in both these examinations to take an exam date according to your own comfort, people tend to stretch more and more. Plan for GRE , then TOEFL. Once you are don with these two, perform shortlisting of colleges and apply to them. Always try to apply as early as possible to increase your chances of acceptance. You have plenty of time. For fall 2015, the univs will open their application portal in October-November. Try to apply as early as possible.

First of all, you asked this question on time. You still have enough time if u plan well. 1) when is the best time to give GRE? For you, best time is end of August. Since, you are working, if u devote 2 to 3 hrs daily, u can easily excel. You can join some online courses like http://www.Greedge.com that will help you to study at your own pace with full support from their staff. They will make a very good study plan for you according to ur needs and schedule. Try to read as much as you can and start working on learning words from now on. U can give test once again in November. Its not too late. Although I will keep November option for second attempt only. 2) When should I apply to universities? Deadlines for many universities vary from December to july. So u will have to check each and every university. Dont wait for the deadline. Apply as early as you can but right now u are not at any disadvantage. You should start researching about universities from now on and try to chat with the professors who are working in your interest field. 3) TOEFL is a very easy exam and one can excel with just one week's preparation. You need not worry abt it. Attempt it after your gre. 4) SOPs LORs are needed at much later stage and ur priority is gre. Although u have enough time And CAT is much more difficult than GRE and it doesn't matter if u have prepared for any exam before. It's an aptitute test and u need to know only basics.
