Guys as the name suggests Bureau if overseas Study, its obviously more into IELTS exams which is mandatory for going abroad. Even I wanted to prepare for IELTS so I joined this class on a friends recommendation, they also have a referral scheme.
The class is very badly managed and does not take lectures regularly. Their mock tests are not at all productive and they do not provide immediate feedback on the same.
Their study material is also not that great, but they do charge a hefty amount for special tutions and for me it was not worth it. I wouldnt recommend this class to people.
