Hello, gate is expected to be conducted in the month of February or March while Cat will be conducted in the month of November. There wont be any clashes in the time slot between them. Cat has been conducted in three slots due to this pandemic prior it was two slots and gate will also be conducted in two slots- 9-12 and 2-5. But there has been instances when the CDS and Gate exam has been conducted in the time slots and unfortunately no relaxation can be made in both the conducting bodies and the candidate can choose to write any one of the exam only.

Best wishes.
