The GMAT is a standardized test administered by GMAC for graduates seeking admission into Business School. On the other hand, ETS administers the GRE for graduates pursuing higher degrees (Masters and PhD). We handle both training and registration for both tests. The duration of training is six weeks. The official guides for both tests are core in our preparation. Because both tests are Computer Adaptive Tests (CAT) we introduce our students to CAT via ICT in order   for them to get acquainted with CAT format. In addition, students take a minimum of two full length tests before they end their programme.


These tests are standardized English tests taken by non-native English speakers in order to obtain admission, visa and get employment in native English-speaking countries. Both tests are designed to determine the proficiency level of test takers in four key areas: writing, speaking, listening and reading. We handle both registration and training for these tests. The duration for preparation is usually two months. Also, a wide range of books and audio-visual learning materials are provided for all our students. Every student takes at least two full length tests before they sit the examination in order to determine their proficiency level.
