    I don't think it makes a difference if it says propan-1,2,3-triol or propane-1,2,3-triol , who is disagreeing? in fact I the correct method is to write propan , look on the CPG revision guide page 68

    Check page 79, they dont do it from the centre, they did it from the dotted line to the bottom of the dot , i did exactly like that, not to centre
    But for the book is it a small spot, or one that is quite long? Because it's okay to measure to the bottom if it's a small spot. But if it's a spot over a distance, it's best to measure from the middle.

    Either way the mark schemes have always accepted both answers.

    Thanks for answering. So the bottom one was kept at the centre right? Also, in my diag there was only only one wedge from my chiral centre, the rest were skeletal lines
    Yeah one wedge and 3 skeletal lines.

    The bottom was kept the same. Just mirror the top around the top choral carbon. Or you could do the bottom one.

    Well the book does not state anything about middle shows clearly from bottom to the dotted lines, clearly with an X I don't think it depends on size of the dot, measure with ruler and check with the other dots same thing

    Hoping for 57/60. Do you think that will be enough for 85/90 UMS?

    I'm pretty sure that'll be high enough but this was quite a very straightforward exam with just a lot of recall of facts really.

    Yeah. I'd still say it was harder than January. Just gotta hope I haven't dropped anymore marks stupidly. and coursework grade boundaries haven't been set yet so I may need more/less UMS :O

    Well the last question was a nice little puzzle and really enjoyed it But yeah I'd say the boundaries will be lower as its a June exam anyway, I'm sure you'll be fine and I'm just going off last years numbers with my 36/40 marks in coursework

    what do you think the boundaries for F325? I have to say F325 is a priority as that consists more mark

    I got 36 too. Used it as 48 UMS. Same as last year. I doubt it would go up. Maybe down if less people have hit those marks.

    36/40 is full UMS, well I did my practicals in summer for A2 and got 37/40 which was full UMS
    They made it 48/60 UMS now. They've gone up in recent years.

    3. 2 were identical. They were salts of the monomers.
