Hi, I would need specific information here:
1.You want to know about London School of Economics or London Business School?
2. What is your background?
3. Do you have a GMAT/GRE score?
4. What is your previous CGPA/GPA?
5. Do you have any work experience?
MBA programs abroad require a GMAT, English proficiency along with an application.
The application itself requires you to answer some questions.

Do revert with more information.
All the best!

Yes you can do but there is eligibility criteria for that. You can visit the site and have a look at the exact criteria for it
