currently im scoring around 60s in dashcats. im only able to solve 1 dilr set instead of 2 and barely able to solve 3-4 quant qs how can i improve my score to around 80 in dashcat as i am targeting a 99%ile in cat? im feeling very demotivated as cat is almost here in less than 45 days and i dont know how to get a grip on my scores.
