    How is it terrible?
    It's just ml+ mc(delta)(tithe)= mc(delta)(tithe) + mc(delta)(tithe)

    Right?

    I love heat , mass given g just mulitply by 10^-3 and for the water and calorimeter temp is final - Initial then the specific of vap or fusion is 100-final ur given heat capacity of water and copper

    Does anyone have a full list of definitions that would get full marks in HL physics?

    how strict is the marking scheme . If you take a logical approach to a question and obtain a reasonable answer will that merit any marks ?

    For a C3 you need 55%, Section A (the experiments) are worth 30%, if you do anything this weekend please learn the experiments!

    For Section B, Mechanics, Modern Physics, WLS and the Option (Particle or Applied Electricity) always appear. I'd focus on those sections if you're looking just for a C3. I'd go over the earlier chapters of Electricity too as there easy and common enough to appear.

    WLS? What is that?

    Waves, Light & Sound, I think.

    Yeah it is, sorry!

    I'm starting to worry about the exam, it's the one subject I care about and I really want to do well :-(

    Hey would I be good with just knowing modern physics, particle physics, electricity/magnetism and mechanics. I plan on doing those questions in section B aswell as short questions. I know them really well and i Know some of heat, light and sound but not as well, I got an A1 in the mock and really hoping I get an A1 in the LC just not too sure if I should bother going over other stuff I might not even need.

    Are you also doing Electrostatics? I'd cover that as well, it could easily come up.

    If you are doing the short questions, there'll probably be 2-3 light, heat and sound questions. It's going to be hard to get good marks in them for an A1.

    I'd suggest you do questions:

    Q. 6 Mechanics
    Modern Physics question
    Particle Physics
    Electricity question
    And question 12.

    Should be fine, really. I'm covering everything but electricity, and looking for an A1 as well.

    Mechanics, WLS, heat, resistance/resistivity. Am I covered?

    I'm looking for a C3/C2 and I'm confident on the experiments but not at all on the long questions would mechanics WLS and particles physics be enough to get me through it ?

    Physics isn't too big we can do it fellas :D
    I would say don't neglect Electricity too much. Is there likely to be a full question on Electromagnetism?

    I would say there will be a full question on it. There has not been a full question on it for years

    Would I be safe if I don't learn the experiments that came up last year??

    You should be. Last year's experiments weren't too bad anyway.

    Wouldn't be surprised if they decided to troll us and put one up from last year though, seems like something they'd do this year ;)

    Yeah I was looking at the papers and the potential difference experiment came up two years in a row.! I'm just trying to eliminate some experiments as I only have today and tomorrow to cram ! :( all I want is a D1 !

    I failed it in the mock but apparently they were all marked wrong :/ just hope I can get a D1 in the next few days

    I think like 98% of the cohort do the Particle Physics option. I really wanted to do Applied Electricity but my teacher said he always did Particle so I just stuck it out...

    I really wish Physics wasn't a 100% written terminal exam. I wish it had some other component in it, like what we did at JC.

    My teacher also does particle but I'm more inclined towards applied so I'll do it.
    I hope there isn't anything novel or new to our exam and its more adapted from past papers like it has been.

    I'd prefer the Electron as a long Modern Physics Q but it looks more like radioactivity will come up :/

    Do you have to know the particles under the particle headings like Leptons, Mesons and Baryons?
