When I said to my instructor, after my first solo, that I missed his couple of hundredweight next to me, he thanked me for the compliment

The difference in weight was such that I just shot upwards at much less power and in the hover, flew very much left skid low (Hughes269 - LHS PIC).
As was said before, if in doubt, go around. But I'll buy you a beer if you do a go around just for the hell of it. You are the captain, so if that is your decision, then your instructor should understand that! I chickened out and landed as I was told to!
But you'll be fine; if you're not ready, your instructor won't let you go. Good Luck.
Cheers
