The most common mistake by students is to be confused between similar looking options. Suggesting a way out, Rishika Sharma, Head of School, Khaitan Public School, Ghaziabad said, “Please read all the options carefully, no matter u know the answer. As options may have some similarities and may confuse at first instance. If two or more option is found similar or correct then try to negotiate what could be the reason for this answer to be incorrect. If u don’t find any reason or u find less reason before you choose the right one. We must do the practice of solving questions during our preparation at board exam time duration."
