Yeah, it is definitely redundant to say "My friends cheered for my progress as much as I did for myself." You do not need the "for myself" part. An alternative would be: "My friends and I cheered for my progress." If you want to emphasize their cheering in comparison to yours, use synonyms that show this or you could rearrange the sentence. For Example: My friends and I were equally cheerful because of my progress. OR My friends cheered for my progress just like I did. You could leave the first one as you have it, but the wording makes the sentence sound a bit redundant. But overall, it is okay. More acceptable when you're speaking, but in writing try to use some of the alternatives I provided. Hope that helped :)

Your first sentence is ok, but "cheered for my progress" is a little awkward. If you use it, don't add "for myself". See below for why. I might say, "as I progressed, my friends cheered for me as much as I did for myself, you could leave out "for myself" here, but I like the parallel structure of "for me" followed by "for myself." Why myself in this case? Here, both you and your friends are cheering for you. In your sentence, your friends are not directly cheering you, but are cheering "your progress". A small difference, but important to make the sentence sound right.

Thank you Muhammed!

I dont know : )
