Some universities accept GCSE (O/L) english C or higher as equal to IELTS 6
UK is getting more students because they have to show funds for 1 year (fees + living costs)
When the year is over if the student has no more money he/she is in trouble
You don't need a agent, all the information is available online
ielts is lot more tougher than gce o/l English
for uk u mi8 nt need a agent but it is good to go through who sm1 knws the subject better...
