@kremitz, mas mabilis ang IELTS, I think (or maybe dito), compared sa skills assessment. Puwede nyo siguro intayin, bago kayo mag IELTS but definitely start the ball rolling for the skills assessment.
Eto, according to IELTS:
<blockquote>IELTS result is only valid for two years from the test date. This is to ensure the reliability of the test results since language skills of individuals may develop or deteriorate in a span of two years.
The IELTS system automatically deactivates IELTS result when it reaches its 2nd year. It is not possible to extend the validity of the IELTS results.</blockquote>
