An online application, academic transcripts, a resume, references, and results from standardised tests (GMAT/GRE and English language skills) are required when applying to Saïd Business School as an overseas student for undergraduate programs. Program-specific requirements differ, but generally speaking, you must have a solid academic record, relevant work experience, and an engaging application essay. 

Academic Transcripts: Send in official transcripts from every school you've ever attended, along with any translations that may be required. 
GMAT/GRE: In most cases, international students must submit their GMAT or GRE results. 
English Language Proficiency: If English is not your first language, you will need to demonstrate your ability to communicate in the language, usually by submitting your TOEFL or IELTS results.
