Dear XX:
l am glad to help you,As for how to study English.Here is my way.
You said that you can't remember words ,I think you can make word cards to
renmember them.It's easy to syudy grammer too,You can take notes and ask teacher
for help .It's very important to handn up in class . It can help you not very
shy to have a conversation with others.Just make sure to try your best ,you can
do every thing you want.People says:"the habit is the best teacher "so,you must
let English to become your habit and must work hard.
I hope my advice will be of some help.
Yours
XX
