Oh Raman don't get panic and frustrated. I was like you in the beginning. It was very difficult to complete one task and increase my balance. But day by day I am being perfect.
What I suggest you is read instruction very carefully and try to task very slowly.
Once you get the momentum you can do quickly. First make your self confidence about the task.
Nothing is wrong and it's not late. Clixsense add's thousand of jobs for you.
So best of Luck Raman.
