I am also applying through general admission and still waiting for the letter. But, not all applicants are going to have a chance. According to Q&As of the School, only 450 will be interviewed, then more than 1,000 (i guess at least 1500 have applied) will be disappointed in the very first round.
I also got the letter for interview next Saturday morning. Our kids have done their best in the past six years to at least get a chance for the interview. Whatever the result is, they are our best. Let's give them our full support as we all have done in the past six years.
