By Law an Employer has a right to change terms of appointment after giving the employee due notice of accepting it or quitting.
Here the Govt has given you option to either pass BA(Eng) or NO HIKE.
This is the right of the Employer
Third option is to quit
Fourth option is to go to a lawyer and jointly go before a Court of Law
Your Union can fight at their level too
Lawyers will always say , YOU have a strong case and if there are 200Employees , they will ask you first 25000 Rs , then 25000 and make it a figure of 5 Lakh whch will burden each around 2000-2500 and the result may come after years. Then whoever looses goes to High Court (Govt at no cost , You again to shell out something) . Then to Supreme Court and again to shell out something
May take 15 to 20 yrs till final outcome comes . Some may see the result from Heavens or Hell , as the case be.
Shortest course is to pass BA(Eng) and be happy and increase your knowledge with pay hike too.
Even if you are entrapped in some Court procedures , get admission in BA(Eng) Pass it and live merrily.
Passing BA(Eng) is easier and cheaper than going thro Court proceedings.
Finally , you are the best judge .
And if an advocate is asking for his client then dont show him this o0r else you will loose a Good client.
