I understand you're asking about the choice filling (option entry) date for Engineering Round 3 counselling in Andhra Pradesh (AP), specifically the web options.

1. Round 3 choice filling usually happens end of August to early September every year.

2. For example, in 2023 it was from August 28 to September 1.

3. You must fill or change your choices online on the official AP CAP website during these dates

4. If you miss the dates, you cannot participate in Round 3 allotment.

5. After choice filling, seat allotment results will come in a few days.

6. This is the last chance to get a seat or change preferences.

Check official site for exact 2025 dates.

Thank you,

best regards from Careers360 team.
