Is the conventional current flow the same direction as the flow of the electrons?

Yes or No?

No.

The flow of electrons is in the opposite side to the flow of convectional current.

Convectional current is considered to be the flow of positive charges from the positive terminal of the cell called anode to the negative terminal of the cell called cathode through the external circuit.

Electrons flow from cathode to the anode of the cell through the external circuit.
