Here are a few things you can try
Thoroughly look into what is implemented in c++ stl.
Implement all the algorithms you've learnt in as many ways as possible.
As you said implementation is your main problem, you might be messing up with the corner cases. Be careful with them.
Try to solve codeforces contest archives. Spend some time on each of them and then look into the editorials. This will help a lot if you plan to take ACM ICPC.

Introduction
The subject Computer Graphics was introduced into the IT syllabus from the 2008 pattern in the 4th semester. Earlier in the 2003 pattern I.T. had computer graphics in the 5th semester under the title 'Multimedia'. Computer Engg had it in the 4th sem of the curriculum even in the 2003 pattern. Syllabus for Comp and IT is quite different, around 3 to 3.5 units in common.
Overview
Computer Grpahics aka CG is a simple and easy to learn subject. Very interesting and also scoring. The subject includes a 100 marks Theory paper , 50 marks practical i.e. CG&OOPL and 50 marks term work. This subject does not need tedious efforts to score even though a major part of this subject is theoretical. Even though 80% of the subject being theoretical it is pretty easy to score 65+ without strenous efforts.And of course,you can definitely score 70+ but it requires quality efforts.
