hi guys, I would greatly appreciate it if you could help me with this code

I have some tables called,

Student (SID,SNAME) -> I have got data into it
Course(CID,CNAME) -> I have got data into it
Take(SID,CID) -> I have got data into it
quesion (CID,QNO,MRKS)-> I have got data into it
answer (SID,CID,QNO,ACTUALMRKS) ->I need to insert data into it?

Now I want to display CID as drop-down menu from Take table

if I select a data from above the drop-down menu then another drop-down menu should create automatically with the SID form Take who is taking particular CID.

If I selected both field then QNO (should come from the question table) and a extra text field (depend on how many QNO has itself) has to create automatically to enter ACTUALMRKS.

if I submit then all data has to store into the answer table

You want help with the code, yet you haven't posted any. Making tables is fine, but you need to show us the php you have so far.
