Serial dilution / dilution series calculation worksheet for A-level Biology. Part of a growing bundle of worksheets aimed at improving maths skill confidence for A-level Biologists. 21 marks of AS/A2 exam style serial dilution / dilution series questions. Full mark scheme and serial dilution explanation/method with worked example included. Of particular relevance to AQA required practicals 3 and 6. However, the questions are not exam board specific and would be useful to any practical involving serial dilutions. Percentage change and Hardy-Weinberg calculation worksheets also available.

40 marks of exam-style questions covering the A-level Biology topic of meiosis. Written for the AQA specification, but the majority of the questions are relevant to all exam boards. Non-disjunction has intentionally been set as the last question, allowing it to be easily removed for those exam boards which don’t include this sub-topic. Questions have been designed with the intention of covering as many permutations as possible with regards to meiosis exam questions, but without repetition. Useful as a homework / self-assessment / revision task before an end-of-topic test. Includes full mark scheme.

Ideal for first lesson back after lockdown for a bit of revision, or for a ‘fun’ end of term activity. Would work for remote learning. Includes a powerpoint for the quiz, a student answer sheet and a teacher MS with follow up questions to go with each picture. Virtually all pictures and questions are relevant to AQA, OCR and Edexcel.

Self-assessment maths and statistics skills booklet aimed at helping those students who do not do A-level Maths/Chemistry/Physics and lack confidence with the maths requirement. Full mark scheme included (full solutions, not just the final answer). Contains 63 marks worth of questions involving: percentage change graph drawing dilution calculations ratios uncertainties logarithms bacterial division calculations standard form magnification rate of reaction unit conversions significant figures chi-squared Student’s t-test Spearman’s rank correlation coefficient Index of diversity Relevant for all exam boards with the exception of the index of diversity question, which uses the AQA/Edexcel equation as opposed to the slightly different equation used for OCR.

UPDATE MAY 2024: This resource has been updated based on more recent mark schemes. Comprehensive revision question and answer tables for section 1 of the AQA AS / A2 Biology specification. Excellent revision resource for self-assessment.

UPDATE June 2024: resource has been updated based on more recent mark schemes. Over 475 revision questions & answers covering the AQA AS Biology specification. Based on past mark schemes (there is no guarantee that future mark schemes will be the same). Comprehensive resource useful for students to test themselves or to enable someone from a non-science background to test them. Please note that I can accept no responsibility for your final exam grade should you choose to use these revision resources. These resources are intended to help students actively revise, but students should be aware that a high proportion of the marks in your exams are AO2 and AO3 marks and students should therefore use a variety of resources and techniques in preparation for all of the question styles that will be encountered in the exam. Whilst these resources have been written with past mark schemes in mind, there is no guarantee that future mark schemes will be the same. Every effort has been made to ensure the accuracy of the information in this resource, but I am only human, so if you spot an error, please email teachsecondaryscience@gmail.com and the resource will be updated ASAP.

Detailed worksheet covering (virtually all) possible autosomal linkage exam questions. Could be used as homework or as an assessment (due to the low number of past exam questions on this particular topic). Includes a chi-squared question and links to/revision of meiosis Made with AQA in mind, but the specifications for OCR and Edexcel are pretty similar for this topic, so would be beneficial to those specifications as well. Mark scheme included.
