 \subsection{What went well?}
 My system worked as intended, it did play the input signal, through the speakers, atfer passing through all the subsystems and the speaker.
-I will compare, line by line, to my design objectives here:
-
+For this I believe I made a good project.
 \subsection{What didn't go well?}
+My colour coding for my system was not ideal, I believe it was too generic and would have benififted from using multiple colours for each sub system. 
+
+I would have prefered to use a less noisy alternative to the push pull power amp, as my system outputed a large amount of static.
+
+I would have prefered to use FM rather than AM, as this would reduce the noise; making the device better.
