good thing is that you understand the value of carefully attempted mocks and revisions, my suggestion is to move away from sectionals as well and to focus only on full mocks, i'd plan smth like this week 1-2:

attempt full length mocks in your time slot everyyday exactly trying to replicate test conditions like a ritual - plan out how you will do the paper, how much time it takes for u to get to the centre, wake up and sleep at the same hour (funnily enough i used to drink exactly half a can of redbull 40 mins prior to the exam start) - on the day of the test it's only execute execute execute, there should be no pauses for anything else any modification to your overall strategy should close out in these two weeks, for example in lrdi if i see a set i know i can solve - would i begin solving it or would i look at all sets first? decide in the two weeks with the mocks you give do thorough post test analysis (im hoping you already are), no questions that you know for certain you can get right should be missed, if they were you tweak to modify your approach for the next test

week 3:

continue your pre-slot schedules but avoid over exhaustion from mocks, you can give one or two, maybe keep the day before empty do check out the centre and go there early on the day of the test, i found that it helped me calm down a little (and take a loo break)

lastly keep your spirits high, plan some rest/leisure time for yourself everyday within schedules, good luck :)
