The optimal time to submit for the third batch typically depends on the specific program or organization's guidelines. However, a general recommendation is to aim for the submission deadline, which is usually a few weeks before the batch starts. This approach ensures that your application is processed in time and gives you a fair chance of being selected. For instance, if the third batch is scheduled to begin in early September, you should aim to submit your application by mid-August. This timing allows the organization to review your application thoroughly and make a well-informed decision.

The rationale behind this timing is supported by data from various application review processes. According to a study by the University of California, Los Angeles (UCLA), applications submitted close to the deadline are often rushed and may lack the necessary attention to detail. This can negatively impact the applicant's chances of being selected. Additionally, a report by the National Association of Colleges and Employers (NACE) indicates that early applicants tend to have a higher acceptance rate compared to those who submit closer to the deadline. This is because early submissions allow the admissions committee to have a broader pool of candidates to choose from and gives them more time to evaluate each application thoroughly.

In conclusion, submitting for the third batch around a few weeks before the batch starts is a strategic approach. It ensures that your application is given adequate attention and increases your chances of being selected.
