can someone please recommend good online mock tests website?

Careerlauncher, IMS and TestFunda are some best mock exam sites. You would require 8-10 months for consideration and preparing well enough. Join a coaching class like TIME, CpLC, Catking, Careerlauncher. You should devote 4 months for full preparation and solve weekly mock exams. After that devoting 1month for mock tests for each section, and then 1month for all sections together. You would need to correct and recrify mistakes and weaknesses should be focussed. In the end, just revision and more mock exams will help you alot. You should solve more problems from books like Arun Sharma, RS agarwal, Chandresh agarwal. Try to give mock tests every week and revise them frequently to avoid mistakes.
