Hello aspirant, as you already know in the current pandemic condition all 10th and 12th board exams have been cancelled nationwide. This is a very new experience for all students and teachers. There won't be any problem in getting admission in top universities as the situation is same for entire 2020 and 2021 batch. The admissions are done on the basis of competitive exams like JEE mains for engineering and NEET UG 2021 for medical students.

The only problem could be lack of proper studying of all topics. Class 11th has many important topics from which questions come in competitive exams. So as long as you work hard and don't waste time you can easily crack the competitive exams. Keep giving mock tests as they will help you to improve your performance.
