  • I found this program very useful. The topics are laid out clearly for ease of reference. It is nothing like your usual revision guide because Jeevan's is a well-defined strategy; he shows you exactly what to do to achieve a top grade in GCSE maths, in a step-by-step format. He addresses issues such as how much time should be spent on revision, exam technique, tips for scoring 100%, motivation, freeing up 50% of your time etc. unlike a normal revision guide which is just packed with theory. He also explains concepts with more detail. For instance, I used to find solving equations tricky but after reading his section on algebra, I fully understand how to solve an equation. The DVDs are great because he teaches concepts both verbally and visually which is always helpful! ◆◆◆ https://bit.ly/33W8jmf
