Dear Raj!

In order to avoid any problem in jee main, either have a new certificate with correct name and also if needed issue an affidavit for the same. While filling the application, you must enter your name as shyam lal instead of shyamlal. If still the problem continues, then you have to go with general category. Then you may not have the benefits of sc category. You have to clear all the eligibility criteria for appearing in the exam and for all further exam, mention that name only which is mentioned in your marksheet.

Hope this will help you.
