I took my PTE in Scicom center few weeks ago. I got the full mark but after these few weeks I still feel responsible to rate their service.
The coordinator was a lady named "Kumari". Unfortunately, she was very impolite and rude towards students for no reason. It was shocking that for such an important test, this center has chosen someone aggressive with no basic manners!
I hope her poor attitude would not affect others and they could have got a good mark like me. However, it is very sad that it obviously can adversely affect students performance for such an important and expensive test.
I purposely waited few weeks before commenting to make sure I m objective and neutral about it but still when I think about it, it is not acceptable.
Do not recommend this center at all!
