It is difficult to say for certain whether your OMR sheet will be rejected due to bubbling the wrong circle in the booklet series column for KCET 2024.

In some cases, OMR sheet evaluation might involve human intervention for discrepancies. If the written booklet series matches the actual booklet and the error seems isolated, they might consider it for evaluation.

There is also a possibility that the OMR sheet gets rejected due to the error, especially if the OMR evaluation is purely machine-based.
