What are my higher education chances abroad given my current work experience and academic background in UK/Ireland for a Bachelor's/Postgraduate?

Yes, your chances for higher education abroad are strong given your profile. With 85% in 12th grade, a four-year bachelor's degree, postgraduate education, and 4 years of work experience, you are well-qualified for undergraduate or postgraduate programs in the UK, Canada, Ireland, and the USA.

You will need to take an IELTS exam (English proficiency test), as it is mandatory for your target countries. Choosing courses related to your work experience will further strengthen your application. Having no academic backlogs and a consistent academic record also works in your favor.
