questions like what is p q r s etc. are very confusing and they should give straightforward questions which are easily understandable...even in maths or reasoning its the same thing......they should not give a whole achievers section test with only diagrams and stuff like whats p whats q......SOF should improve their questions....also They should make their site better....the site is so boring and we don't feel like taking tests...the site is so outdated...not even designed properly....there are always pictures for diagrams in maths or science questions.....very bad questions and content
