Can i take my snap score from 22 to 35+ in 5 days ?

if you think you can then yes if no then not

i would suggest target 2 sections you feel you are good at. normally for someone attending all sections, it would be suggested 10mins Verbal + 25mins LR + 25mins Quants now I am more comfortable with non verbal so I take it 5 + 25 + 30 instead and try to cover around 45 to 48 questions and end up getting on average around 34 or something .. now similarly you can plan and split the time and also within the section there is no need to attend all, remember these are exams for elimination so there are sitters which you cannot miss in a section try to opt ones you can solve within 45sec and proceed into next ones, hope this helps

yaa i am also getting only 20 marks

focus on LR seeing the time you can maximise your score in this section do 20 question for each critical reasoning daily and revise quants cover grammer and compound words , figures of speech , prefix sufix
