Yes I'll enlist down the top exams and their dates for admission into Foreign Universities..

1. SAT EXAM - dates this year - 2nd May 2020 and June 6th. The registration for the same will be done on April 3 and May 8 respectively. https://studyabroad.careers360.com/articles/sat
2. GRE EXAM - The test dates are April 4, September 14 and October 26. The registration dates for the same are February 21, August 2 and September 13 respectively. https://studyabroad.careers360.com/exams/gre
3. TOEFL - You can choose the dates yourself. Your target date for taking the TOEFL exam should be at least a month before your first application deadline. This will give you plenty of time to work on your applications, and in case you need to retake the exam you can do so after 12 days of the first attempt. https://studyabroad.careers360.com/exams/toefl
4. IELTS EXAM - you can choose the dates for this exam once again by yourself only. Here is the official link for the same. Attached at the bottom https://studyabroad.careers360.com/exams/ielts
