I'd say either the windscreen or the bonnet will come up for marking out.
Also, have a design ready (rough sketch) of the design part of the project- the control console (you wouldn't need to show measurements).
Understand how the electronic circuit operates.
We were asked in our Mock to identify 2 aerodynamic features also- that would be the bonnet and the spoiler.
Best of luck on Tuesday:)
Also can I just ask if there's any hope of getting an A for me? My project was completely assembled but I didn't get to polish the parts or wire the circuit fully, my practical was completely finished, sanded and functional. I got 93/100 in the Mock and hopefully might get another mark or 2 on Tuesday. Is there any hope left (considering what I got done for the project and practical)?
