Earlier we have explained this in a summary way so many of us have mailed me to add screenshots. So I'm adding screenshots and explaining it in a detailed way on How to apply for Group 2a classes in Manidhaneyam. Step 1: Go to http://saidais.com and look for "free coaching registration for TNPSC Group 2a in Manidhanaeyam". Click on the link Step 2: Fill the form which is asks for very basic details like Name, Email Id, Mobile Number, Date of Birth, Gender, Education, Religion, Community, Caste and captcha where as filling application form for TNPSC will make us mad. Step 3: You will get the confirmation message that you have successfully registered in Manidhanaeyam Coaching. You will also get a mail from Manidhanaeyam for Successful registration. Note: There won't be any username, password, Register number or OTP for this registration. Don't get diverted. Use this simple procedure to register.
