hii sat mine a few days ago and got 3040 band 1
i really didn’t like DM either, i found the best way was to go through each question type one by one untimed at first until you feel like you’ve mastered them (break it down) - also watch youtubers do the questions
QR make sure u are extremely comfortable using keyboard shortcuts and the number pad, look at the actual question first and then the question stem if you are given a whole bunch of data, don’t get lost in the data!! only relevant stuff!! also make sure u are 100% with unit conversions (cm/m/ml/l etc.)u want it to basically become second nature ,
be really comfortable with percentages, ratios, look out for cumulative data
i scored best in my QR so hopefully this helps ahhhh good luck u will smash it !
