The 6BI01 unit, like all other main units, it worth 120 UMS points. The raw score, like all other main units, is 80 marks. Units 3(B) and 6(B) are worth 60 UMS. Unit 3B's raw score is 40 and 6B's is 50.
In AS, 6BI01 is worth 40% of the total grade earned! In the full A Level, this unit is worth 20%. So, it it clear that this unit is heavily weighted in the AS year so you should try you best to perform well. This is a fairly simple and straightforward unit. If you learn the concepts and familiarise yourself with previous questions and how they are answered you should earn yourself a nice, solid A. I scored 101/120 in this unit, but I had the potential to score 120/120. I underestimated the time factor and omitted lots of raw marks because time ran out. I knew the answers to to the questions I left out! I sat this unit in June 2009 and the time for this paper was 1 hour 15 minutes. The examiners realised that we were pressed for time so they increase the time for this paper to 1 hour 30 minutes. The raw marks remain unchanged.
