Assalamualaikum
Hope this will help u gais lah ye, In Shaa Allah
So basically, my english is not flawless but there are some tips that I can share with you guys
1) start with the most basic things
Kenal pasti cara guna yang paling biasa akan digunakan
The,is,are, semua tu then please jangan tertukar singular and plural, past tense and present tense semua, senang cerita kena tahu basic rules
work on your grmmar- buat latihan!
2) dengar lagu, ikut sekali sambil tengok lyrics ;)
3)kalau rajin, tengok english movie takde subs first then tengok sekali lagi yang ada subs to measure your understanding khenn
4) instead of dgar radio (english channels-flyfm,hitz etc)
for nothing, cer try ikut dj radio tu cakap, aku suka buat balik dlu to work on my accent, actually accent tak penting pun, sebutan tu je taknakla memalukan diri kita nanti kan, at least tau haha
5) try to speak with others, memang malu, lama lama kalisss la, sampai bila nak malu, ye dok?
Hope it helps, I do believe that if you put much effort, In Shaa Allah you are going to succeed as once I used to practise like what I have stated before and now English is not my nightmare anymore! In fact I love english
