My Target is to crack IAS,Is it good to drop one year for CLAT coaching (for bsc LLB) after 12 then prepare for IAS. Or should i do BSC

While it is not impossible, it is a really challenging task. To score well, you must start preparing for CLAT at least six months before. It is very important to score well if you are looking forward to getting into good NLU. For top 10 NLU, you at least need to score between 100 to 105 as per past trends.

The CLAT Syllabus is published by the Consortium. The syllabus has been announced. Candidates who are preparing for the exam must note that there are no changes made in the syllabus so far.  Candidates can check the syllabus by visiting the official website. You can only download the PDF from website.

To know if you are eligible for CLAT Exam or not you can visit the official website and check the notification. The notification which was earlier released by the consortium carries all important details like elgibility criteria, fees, exam dates etc. Once you have checked if you are eligible to appear or not then only you should fill the form. 

You don't have to worry. In case you have forgotten your ID and password, which is pretty much normal. You can go and click on the forgot password tab in the registration window. You will receive the mail and then you have to reset your password. Once day you will be able to login. 

See, it doesn't matter that you fill the form through laptop or phone. What matters is you fill the form. Yes, you should have good network connection and internet speed. It should not happen that you have filled the form and when you reach the last step you loose the connection. So what is important is network connection not the phone or laptop to fill the application form.
