Hi and welcome to GMATClub
Well... U will progress for sure if u put enough of dedication to GMAT
... Do u have the OG 11
Once u work with this book, u have a better idea of what the GMAT questions are. Often tricky on 1 point, u will observe that u need to read with a whole attention the question and statments. It's one of the important things to do in order to avoid "silly" mistakes.
Also, your background will revive in u but it could bomb u by doing wrong assumptions... Especially with the question itself : understand i, n or l like integers when they are not and so on
Finally, good luck ! :D
... Don't forget that participating on the V & Q sections of GMATClub is the key of success
