    how much do we need to know about plant defenses? my textbook has many different plant defenses and names for the chemicals produced, should i learn those?
    also how much should we know about laser confocal microscopes?

    When you say plant defenses what exactly are you referring to? Laser confocal Ive literally learnt that they use point illumination which cause neon colours to glow due to the fact the specimen is tagged with a fluorescent dye. They can show different depths have a high resolution and are non-invasive. That's all I've learnt

    the production of callose, and names of insect repellents/anti-fungals/etc. if i recall correctly this is the new part of the spec

    and okay that's literally all i know too!! the other thing i forgot to mention was biosensors... how much should i know about that because i've honestly forgotten about it lol

    Ngl I have no idea about plant defense Im pretty sure that isn't on the new spec as I only went over the spec a couple of days ago and I definitely don't remember seeing that on it! Not entirely sure regarding biosensors I have learnt: They can be used to test chemicals in a solution. It uses a biological molecule to detect a chemical. The biological molecule produces a signal which is converted to an electrical signal by a transducer. The electrical signal is then processed to work out other info (e.g. initial concentration)

    They just released some new mcq's last week on the exam board site. Not sure if it's available for students though so you might need to ask your teacher for it.

    Look at the teaching resources, they also have some task materials.

    Same! I can't believe English Lit and Biology are on the same day, they're my worst exams, fml

    Check out the old spec papers.
    Also edexcel and AQA board have similar examination style questions. Edexcel contains some multiple choice questions as well

    So is it unlikely they will ask like explain step by step how to do a serial dilution and instead maybe just say like name the procedure/method the student has done or like suggest an experiment the student could do?
    Yeah. I'd definitely know what a serial dilution is, but it's more than you can say you could use it as part of an experiment plan than be tested directly on it. It could maybe be in the multiple choice section as a "which is a valid technnique" I'd guess though.

    Hi Guys,
    i was wondering what your predictions are for the longer mark questions. For example, i feel like the examiners are going to put in a question asking us to describe the the cardiac cycle, or to explain the process of Translocation and transpiration.
    What do you think?
    I would love it if there is a question on immunity, as there is a lot of things that you can mention. Also, evidence for evolution might come up but that could be too simple. As long as they are not practical related I am fine really.
    However, possible 6 markers in my opinion is;
    Cardiac cycle, the transport of oxygen and carbon dioxide, translocation, transpiration, immunity.

    The specification highlighted tylose formation, callose deposition, stomatal closing and production of chemicals such as alkaloids as their reference. Mentioning these keywords with a brief explanation will get you the marks in my opinion.

    The CGP biology revision guide for the new specification is absolutely incredible. It is exactly according to the specification- I can safely say CGP has never released a more spot on revision guide. Seriously the best revision guide. Just go to a shop and check it out- you will not be disappointed!

    I agree with this so much!!! Literally so nice and condensed and not loads of info you don't need to know like the textbooks!!!
