I have a few resits to do in the summer and I am ashamed as I did not do well in my exams but I am also trying

to make new friends at a kickboxing club that I joined but what if they find out about my resits?I mean what if they ask me how I am doing on my course what do I tell them?They might think I am bit slow and not want to be friends with me, what do I do?I mean to lie is wrong.
