Hello

If you want to study abroad then TOEFL is for you TOELF is like IELTS but IELTS is more wodely used.

You have to apply in various universities abroad along with your TOEFL but you have to see if the university you are applying in is accepting TOEFL. Depending on the course you want to take admission in you have to give exams seperately.

Other exams would be IELTS for english, GMAT for MBA.

if you have any more questions I would be happy to answer them in the comments.

Hope it helps.

Hii..

Seems like you are interested in studying abroad for masters. 

Some of the most popular, and most important, international entrance exams for abroad studies include the SAT, MCAT, LSAT, GMAT, GRE, IELTS and the TOEFL. These are required for admission to universities and colleges in various countries across the globe; at times, the need may be a combination of one or more of these and other tests/examinations specific to that country and its education system.The TOEFL and the IELTS probably top the list with regard to the sheer number of students across the world needing to undertake one or the other to demonstrate English language proficiency. The widest possible selection of universities and colleges accept TOEFL scores, including the top 100 in the UK, U.S, Canada, Australia and New Zealand. The IELTS is a mandatory exam for Indian and other non-native English speakers, especially in the Commonwealth countries, for entry into most reputed universities and colleges overseas, and occasionally for immigration requirements as well.The TOEFL is held throughout the year, usually on weekends; the TOEFL is to be held only on weekends, both in the metros and the tier 2 and tier 3 cities. To take up IELTS, you can book your slot at any recognised IDP test centres. 

Hope it helps.
