    7:02 wouldn't you also need to state that you'd use varying conc of the enzyme as the independent variable?

    • @igbiocomplete
      @igbiocomplete  7 місяців тому +1

      No. Because we are not actively varying enzyme concentration, you won't get a mark for mentioning the independent variable.

    Hi, at 8:16, is the line meant to be connecting all points or should it be a line of best fit? I was told to do a best fit line but I am uncertain. Thanks!

    • @igbiocomplete
      @igbiocomplete  7 місяців тому

      Joining plotted points with ruled straight lines is sufficient (unless the question specifically asks for a line of best fit).

    Great video as always!!! I genuinely believe that im ready for paper 6 now...... 2 questions tho.. can some tables contain only one named raw heading?? And is the independent variable always to the left of the table?

    • @igbiocomplete
      @igbiocomplete  7 місяців тому

      Not sure about your first question, need some context. IV should be on the left, yes.

    hello sir. for 1c, do I need to write it out in chronological order as in what step I will take after what or can I simply list out the variables, and methods used like you did for the actual exam?

      Doesn't matter. As long as you the points included in the mark scheme.

    i wanted to ask how do we draw bar graphs in paper 6 as my teacher said htat there has to be equal space between the first bar and the margin as well as between each bar and alo between the last bar and the margin. is that correct? and how do i find out the spacing required

    • @igbiocomplete
      @igbiocomplete  7 місяців тому

      As long as the bars do not touch and are all the same width, you will get the mark.

      No extrapolation. Ruler or curve is fine. Mark schemes simply cite 'suitable line drawn'
