Are there options available when filling the application form, as I did not find any in UK/New Zealand for a Master's?

It depends on the university and country - application forms for master's programs in the UK, UAE, New Zealand, and Germany may not always have dedicated fields for backlogs or gap years.

Most online applications include a section for additional information or a personal statement. You can use this space to explain backlogs or academic gaps. Some universities may also request supporting documents or specific explanations if they find gaps in your academic history.
