Hi,
this ielts score is not good and not bad
for more details ..you must share your overall profile with us ..
if any university or college accept this score with ESL program then you can apply for sp
but chances are bit low,, but its not impossible to get sp
if your brother do not want to retake ielts then you can try..
many of students get visa with this score.
getting student visa is not completely depend on ielts score ..
there are many other things ..like your academic scores ,,Luck
if you gonna apply with this i would like to suggest you to write strong SOP
hope you understand.... Best of luck
