Hi Shaik,

Almost all type of competitive exam athourities gave a platform to students to raise their objections against the officially published answer keys to sort the errors or queries, if any. And for this purpose 2-3 weeks before the announcements of the results of any competitive exam the particular official site opens its windows for candidates to report their respective errors or you can say to challenge the answer key.

Similar is the case with ts pgcet, they also give each candidate a chance to lock their challanges against the answer keys before the release of results for which the publishes an official notice on their site with dates.

But right now, there is no such notice is out.

So, i will suggest you to keep an eye on their official site to get the exact dates to raise your objections.

Good luck.
