You can still make it with determination and hard work. I had a similar scenario during undergraduate days; started with 3.91 in year 1 but eventually graduated with a first class degree in one of the engineering courses.

Having A's in all courses should be your target every semester, even if you would make it, you should be close to the target. Grades from 'C' and below should be avoided as much as possible.

Be consistent, start early while others are resting, use past questions as study guide and have a fellow mate you can share ideals with (one that does not claim to know it all). Above all do not lean on you own strength; always pray for wisdom and grace!

Lest I forget, also learn a skill!
