Did I overestimate my ability?

I overestimated my ability of English through TOEFL.

Maybe I should say I allow some shortages still exist and did not remove them:

I have difficulties to finish reading test on time, to understand the content of classes in listening part of TOEFL, I still have grammar error when I speak

-------------

I almost give up memorizing vocabularies......
because I didn't follow up the schedule well...
but what can i do?
the path to the high score is to practice every day.

Don't give up your practice through keeping and thinking again why I wanted to do it.

Don't be regret in the future.
Practice today and you will thank yourself in the future.

-------------

Seize time and opportunities.

To give up something also is a wisdom and bravery
