Hey Shailja.

Try to focus more on your Boards for now. You can start preparing fully for CLAT after your boards. During your boards and preparation holidays just make sure that you read the newspaper daily for Current affairs and Vocabulary. Try focus on your GK mainly along with your boards preparation. Whenever you have time you can practice some legal aptitude and quantitative aptitude questions and leave the rest for later. Hence prepare for your boards and side by side prepare GK as it won't take too much time. Whenever you have extra time That's when you can take up other sections.

Best of luck
