I'd say reassure. Though I've never heard of one being twice the size (though I guess this is more feasible in the pubertal stage), one being larger than the other and a different tanner stage isn't uncommon during puberty.
Can someone who has taken the exam give me a general idea of how many ehtics questions they are. I know it varies but I am debating if I should read an ethic books that will two days and if its worth it. Only have 14 days left and 2 days is alot so wanted to know if its worth the time for the amount of questions
