I want someone to create a website. It needs to have a software which autochecks the answers given by students to my questions. I want it to be created in a way that i am able to upload thousands of questions online with key to the answer of the question and some keywords. The app must be able to analyze the student's answer and see if the answer in the text corresponds to the text in the key. If the two match upto a certain percentage say 80% to 90% the student gets highest marks. If the percentage of text matching decreases then the app must give lower marks to the student. Then, there will be some keywords provided for every answer, if the student writes the keywords in his answer then he will get marks but if he does not write them he will lose marks. Then grammatical and spelling mistakes must also be checked. Then, the app must also mark the mistakes of the students by red circles around wrongly written sentences and words and give short suggestions to improve their answers. You need to create a website which is very easy to use. I will make the milestone payment before the website is launched.
