Not able to solve questions under timer

Don’t try to solve everything under a timer from the start practice topic-wise first then do topic sets and gradually increase the pressure an guve sectionals then mocks in mocks if a question looks time consuming leave it and move on instead of getting stuck the more you practice with a timer the less stressful it’ll feel

Practice on mocks and it is not necessary to attempt all the questions just do what you feel you can solve and get the answer like arithmetic so that you can clear the sectional cutoff.
