I did CSi, the notes are on the web so you dont have to turn up to the lecture which was on tues 5-6, n the practicals were really fun anyway, fingerprinting, handwriting analysis, making drug models.
I also did Reading between the lines, i found it quite boring as it was more about media n politics than i anticipated and was quite dull. Although it didnt have an exam, so that was a bonus. You do have to write a diary though saying what was discussed in each lecture, so you have to turn up or get notes off someone else there, although they do take a register. Then you have to write a 1500 essay on something media and how it is interpreted related. Easy to pass if you turn up to the lectures which was on wed 12-2.
