In contrast with the Indian education system, universities, institutes and colleges abroad have multiple intakes over the course of the academic year.
In case you miss a Fall intake you can always apply for the Spring intake. The Fall intake typically begins in September and Spring in January. In some cases, universities may also offer a Summer intake that is in April. These intakes are also decided on the type of programme, and it is best to confirm the dates on the official website of your chosen university.
The two-intake system has been devised to accommodate the large number of students admitted to an institution. It is also useful for students who might have various constraints in joining during a particular intake.
Indian students largely opt for the Fall intake; however, it is important to consider your own needs before making a decision. If you are not able to complete all formalities a month before the intake begins, you can also defer your admission join university during the next intake. Certain courses and universities can also offer you to join maybe a week or two later from case to case.
