Dear Anjali, within Stanford you have English Majors and Minors both which are  BA degree. To be eligible for that course, you need to score good in TOEFL. This is a 4 year, full time course with a tution fees of 14,500 Pounds approximately. However for September 2019 intake, the deadline has been closed.
For the next intake, you need to be ready. You will need absolutely too good grades to get into Stanford. You can apply to Stanford either through Coalition Application or Common Application.
When you apply to Stanford, you apply to the University as whole and not for any particular course or Department. So it is important to mention your preferred majors and interests.
Along with that you will need a strong Statement of Purpose, outstanding essays and Recommendation letters. You will need to keep your school report, Counsellor letter of recommendation, Official transcripts and Letters of recommendation from atleast 2 teachers handy. Any co-curricular activities can be recorded under Optional Art Portfolio.
The Coalition Application/Common Application will have personal essay prompts followed by Stanford questions. You need to write an essay between 300-400 words and not beyond 500-550 words. Then there is Stanford Short Essay Questions which need to be answered in a minimum of 100 words and not beyond 250 words.
Then there is Standardised Testing which tests your accademic preparedness. While no score is minimum, no score guarantees you a seat either.
All the Official Transcripts from Class 9 to 12 need to be submitted either by a Councellor or school officials. You can use the Coalition/Common Applucation to submit these documents. Then there is an optional Interview. This will be a conversation that you will have with an Alumnin of Stanford to clear your doubts and he/she will check what difference can your application to Stanford make.
Finally, you are informed about your Application status.

Hey, to get into Stanford University in any discipline you will need a good grade. They are very selective about their admission so not only your grades but you will have to stand out when you write the application for the University. You will need extracurricular activities that define who you are and your uniqueness. They look out for such students. You will also be required to sit for the SAT test in case they ask for it and also to apply for other university abroad. Some of the links below will help you make up your mind, the links are from their official site so you need to check them out. It will make it clear for you.
