I have several attempts in IELTS. Below are my scores :
My personal analysis, whenever I score well in Reading / Listening the drop the score by 0.5 in Writing.
L/R/W/S : 8.5/6/6.5/7 - Delhi / IDP
L/R/W/S : 8/6/7/6.5 - Ludhiana / BC
L/R/W/S : 7.5/7.5/7/7 - Delhi / IDP
L/R/W/S : 8.5/7/6.5/8 - Delhi / IDP / Revaluation : No Success
L/R/W/S : 8/7/6.5/7 - Delhi / IDP / Revaluation : No Success
L/R/W/S : 7.5/6.5/7/7.5 - Delhi / BC
L/R/W/S : 8.5/8/6.5/7.5 - Jalandhar / BC / Revaluation : Awaiting on the results
I feel they intentionally drop the score by 0.5. Not sure if the system is compromised to block the candidates to apply for Immigration.
