Dear student,

Yes it can cause you alot of problems as you full names is an identity of you as a whole person on that marksheet. Otherwise it won't be considered as yours since the data is missing. So please correct your certificate as quick as possible. KEEP all your documents with all the correct and necessary  information.

The class 10th and 12th marksheets are really important for various academic ducumentations in further studies. So, it is really important you get you surname added to you 10th results as soon as possible. Because there are chances you might have trouble in future.
10th board marksheets are mainly used for age verification but sometimes 10th and 12th marksheets are needed for name verification also.
