Your instructor probably has a good idea what to work on with you, but it never hurts to work isolation training to improve a given skillset.

You can work striking by having a partner throw strikes while you defend or evade only, and then switch roles. You can work takedowns the same way - partner tries to take you down, you sprawl or underhook etc, then switch roles. Work escaping the mount on the ground/holding top position, taking turns. Lots of things you can do to imprive your skills before you start trying to integrate everything in full sparring.

Have fun wth it. smile
