Could someone please help with a Quant strategy to me. I am aware of this strategy that you should first attempt absolute sitters and then go for medium level ones. But somehow during the mock, I always end up going in sequence and some or the easy looking questions baits me into spending more time.

Hi As you said you end up solving in sequence and missing very easy questions , so in my opinion you can try a method where you solve all questions from the topic which is your strength or more confident of irrespective of difficulty . For ex If Arithmetic is your strength then go for arithmetic first , if algebra then go for algebra first , this will boost your confidence otherwise identifying easy questions and solving them first is a good approach , try to give a question a minute or half and if you feel you can make it then go for it , and also keep in mind don't spend more than 2.5minutes on any question .
