If you cleared your backlog in the last semester of engineering at Anna University, your degree certificate will typically be issued after the completion of the next semester's results and the subsequent processing.

This process usually takes about 2 to 3 months after the final semester results are declared.

Since your convocation is next week, you may not receive your degree certificate immediately due to the backlog situation, but it should be available within a few months following the completion of all formalities.

For the most accurate timeline, it's best to contact your college's administration or the examination office directly.
