Answer:
Rewriting the sentence with appropriate and courteous punctuations and capitalization:
What! You got an 'A' on your report? That is awesome! I am really excited for you. Next time, you have to help me with my report.
Step-by-step explanation:
Grammatically, it is not correct to use more than one punctuation mark. The letters that are capitalized are the ones that begin a sentence. The use of the single quotes on "A" differentiates it as a thing in the sentence and not just an alphabet.
