Mkp, Yes, if you have written the obtained CGPA wrong or have committed a mistake in entering the total/out of CGPA in the application form of an examination or an institution, then it is a mistake which may affect your selection, because the selection authorities may deem you to be misinterpreting/misreporting your credentials and hence may affect your chances. Although, if the class 10 marks are not included in the eligibility criteria and selection process and the application form asked for your educational board,then maybe you won't have any problems but that is not certain always. So, it is better to look for the correction of your application form or any other similar procedures to correct the entries or the application form if you are certain to have committed the mistake. Also, you can contact the exam or college authorities through the help desk numbers and inform them about your situation and ask them for any help.
