Hello Sachin
You can definitely give the mock test and just don't limit yourself to a particular site. Practice as much as you can, revise your concepts, strenghten your weak topics and stay determined.
All the best for your future.

hey,

yiu can give mock tests. its the peak time and it'll be good if you do more mock test. analyse your mistakes and weak point and work on them rather revising full syllabus. 

further queries ask in comment.

good luck

Hi Sachin,

If you feel you're confident of your preparation and you feel you would like to test yourself only then attempt the mock test else it is advisable that you complete your syllabus and only then try attempting the mock test otherwise it would hamper your confidence.

The mock test level is very much similar or in some cases higher to actaul JEE Main exam so don't get disheartened if you couldn't score as per your expectations.

Hope it helped. :)

All the best!
