IBT TOEFL Test of English as a foreign Language
The iBT is about as cutting edge as a proficiency test gets. With a radically new platform and futuristic test delivery, the iBT is the most exciting thing to happen to the world of exam testing in decades.
The iBT is substantially different from the CBT (Computer Based TOEFL) in that it has an 'integrated' testing platform. This new platform integrates linguistic skills in an environ that is a close replication of the classroom atmosphere. The purpose of this new innovation in testing is to give score receivers a better idea of how well speakers of other languages will do in an academic setting where English is the first language.
However, all the modules of the TOEFL have not been 'integrated'. Students are only expected to show the skills of integrating different sources of information in the 'Writing' and 'Speaking' Sections.
The iBT will be introduced in Nepal in April 2006 and will immediately impact the testing environ in Nepal. All universities that accepted CBT scores will continue giving validity to CBT scores till they expire and will also accept iBT scores from
students in Nepal who have given this new test post April 2006. The is also no cost
rise in the administration of the iBT with a reasonable cost of $140.

IELTS (International English Language Testing System)
The IELTS is an entry level test in several English speaking countries in the world.
It is a test of English proficiency that is mainly valid in England, Australia and New Zealand. However, increasing numbers of institutions in the United States have also begun accepting IELTS scores as an alternative to the TOEFL.
IELTS is administered by the UCLES (University of Cambridge Local Exam Syndicate) and IDP, Australia. In Nepal, the IELTS is administered by the British Council. The British Council in Kathmandu often uses 'outside' testing centers like the 'British School' and 'The Blue Star Hotel'.

SAT (Scholastic Admission Test)
The SAT is an entry level test for prospective undergraduates. While there are many colleges and universities in the United States that accept foreign students on the basis of their TOEFL scores, the better state universities and private universities require a certain score in the SAT 1 before they can admit any student- domestic or international. The SAT 1 is also one of the criteria that are used to evaluate scholarship applications. A good SAT 1 score goes a long way in ensuring that you get a scholarship award in the institution of your dreams. The SAT 1 is a 'scholastic' test.

It is more esoteric than a proficiency test like the TOEFL and is supposed to measure your aptitude in 'scholastics'. Earlier, the SAT was the acronym for 'Scholastic Aptitude Testing' but in the latest bulletins, this 'full form' can is no longer found on any of the official publications or media.
Classes are conducted from Monday to Friday for a total of Two hours daily. Every Day, one hour each is allotted to the Verbal portion (reading and writing) and the Math portion. Sunday is for full length testing and dedicated testing. Dedicated testing means that students are tested only on question types that they have covered in class. A dedicated test in useful in that, it pinpoints the weaknesses of the student in particular areas.

GRE (Graduate Record Examination Test)
