PLEASE READ CAREFULLY THE FOLLOWING POINTS before using my Edexcel 9-1 GCSE science pages

  1. ALL my unofficial GCSE (Grade 9-1) revision help summaries are based on the NEW 2016 official Edexcel (Grade 9-1) GCSE PHYSICS/combined science physics specifications.

  2. Make sure you know whether you are doing separate science Edexcel GCSE grade 9-1 PHYSICS OR Edexcel GCSE grade 9-1 Combined Science physics.

  3. Also, make sure you know whether you are entered for a higher tier (HT) or a foundation tier (FT) Edexcel GCSE science-physics course, so watch out for the (HT only) 'markers'.

  4. I hope my revision pages help as you get to know my website, its very big and not always easy to navigate, but it is no substitute for making good lesson notes, trying your best on homework questions, studying your textbook, doing past papers of Edexcel GCSE combined science/physics for exam question practice and, above all, attentive to your teacher's teaching!

  5. I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4. above. Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long!
  6. Edexcel  GCSE grade 9-1 Combined Science physics 2 PAST PAPERS and specimen practice paper questions

  7. 'Doc b's chemistry' is a big website so the Google [SEARCH] box at the bottom of each index or revision notes page can be VERY USEFUL - sometimes its better than the indexes for finding things!
