Round Study

7 or above is a decent band to pursue studies or work in England. There are 2 types of IELTS exams accepted in the UK, Standard IELTS and IELTS UK-VI.

1. If you plan to go for work, you will have to take IELTS General; it depends on the profession you choose.
2. If you plan to go for studies, you will have to take IELTS Academic, which depends on the university or college intake requirement. Either way, I suggest you do thorough research or ask someone who has already gone through this process.

I hope this helps.

I think the best way to learn a particular accent is to expose yourself to an environment that makes you practice it in day-to-day life. So, going through Netflix, British radio, and podcasts are good ways to understand how others are doing it, but learning won't be as effective until you practice it regularly.
I suggest joining some speaking groups on social media or finding people with similar interests to practice and listening to podcasts or streaming services.
