Hii lingesha,

don't worry about it.

First of all gather your confidense.no one never-ever lost every thinng.

at this time you should only practice previous year question papers.

you have approximate 1 and 1/2 month.

so from today practice one year question paper every day.

and the questions you will be not able to solve.remember them.

in statrting it will be very difficult for you but after 10 days you will see the benifits.

also you can see vedios lactures on YouTube.

hope you understand

thank you
