did 是past tense过去式,所以后面的动词要present tense进行式,所以learnt要换成learn。
For example,“How did you do that?”,“How did you know?”。
before,在句子后面,意思是“曾经”,
For example,“Have we met before?”,“Have you been there before?”。
所以用previously会比较恰当。
I learned my English during my school days. I had tuition when I was in high school. Since my foundation programme, everything is in English.
