If you are planning to study abroad, you must apply at least 4 to 5 months before the course commences, as the admission procedure takes at least 4 to 5 weeks, visa procedure takes another 5 to 6 weeks approx., and it varies from country to country. Besides you would also need some time for your own preparation such as shopping for personal belongings, meet your relatives before you depart to your new study destination. In some cases, the entire process can be completed in a month. In some cases it may take a year to complete the entire admission process from application to acceptance and start of classes. In any case, start early.
