I hope I'm fine for putting this under travels. I am a fresher in This, I want to apply for a masters programme in one of the universities in the US, and it seems a bit confusing and difficult. No ielts, no Toefl, and no Gre, please how can I start? I don't want to use any agency because of scammers, but if you have a genuine and truthful one, you can help comment on this post. Thank you.

Good evening, i am new here and having scrolled up i will love to ask a few questions here and I'll be grateful if my questions are answered. Thank you.
1. Apart from the ieltsbuddy.com, is there any other site to practise ielts?
2. Can I use ielts to get resident visa in Canada?
3. I am married, does husband needs to write the exam for us to get the Visa.
4. I heard of WES and IQAS, please what's the difference?
Thank you sirs and mas
