In the UK
UK is
preferred for many students for higher studies because of its rich history,
quality education and short programme (3 yrs undergraduate, 1 yr MS and 3 yr
PhD) and due to requirements of IELTS only compared to TOEFL and GRE in the US.
Usual IELTS requirement is 6.5+, depending on the university. Bangladeshi
student generally prefers first four universities in the list. Funding will be
difficult unless you are very talented with research value or under government
scholarship.
