“do u rly thunk hashem will ask youhow did u do in math? No Moshe rabbinu avrohom yaakov yitzchak etc didn’t learn math and I guarantee u that therein the best place!!!!”
Moshe built the mishkan…not sure how he could’ve done the measurements without some grasp of math.
Hashem will not ask you how you did in math but it is likely you will be asked if you tried your best. But if you’re getting physically sick from the stress, chances are you’re doing too much.
