Basically assignment was to create a counter using JK triggers and the 7 segment display should count down from 13(d) to 0. Problem i am facing with is that i made this scheme with parallel transmission, but i need to have sequential transmission. Can you help me with that? Also if i press reset then it shows "0" but it should show "d".

Tell us what the circuit is doing wrong.

I have never heard of parallel or serial transmission. Can you post a reference to the definition?
Also if i press reset then it shows "0" but it should show "d".
Where is the reset button? Your flip flops don't have a set or reset input.

It would be helpful if you posted the complete text for the problem. Translate if necessary.

EDIT: Please clarify the connections circled in red.

Unnecessary wire jogs make your schematic more difficult to read.

It would helpful if you also posted your truth table and kmaps.
