how can I apply directly to universities in the us, uk, and canada without using agents or admission services
You can directly apply to universities in the US, UK, or Canada without agents. You need to identify the universities and programs which match your academic goals. Most universities have detailed application guidelines on their official websites. So, you need to see if you qualify for your program or not. Usually, it will involve transcripts of your previous academic credentials, standardized test scores such as the GRE, GMAT among others, English proficiency test like IELTS/TOEFL, recommendation letters, and your SOP. Once all the documents are prepared, an account on the university application portal is created and you can pitch an application. Also, monitor deadlines for application and scholarship opportunities.
