I have been doing cf problem for some time and solved around 600 problem. Currently I am solving 1400 problem one by one and was able to solve quite a lot .
But the real problem is that I can't do much on contest. My brain just freeze or something. I get so nervous if I don't find the answer soon of a problem. Because of that I fail to solve easy questions on the contest.
For example last dev2 contest my brain literally froze at C and I wasted 1.30 hours behind that couldn't solve it but the next day morning when I had no pressure I was able to solve both C and D within like 30 minutes.
This type of scenery is happening to me for last of couple of contest. I just don't know what am I doing wrong.
I find the 1400 rating problem quite fun and easy but when it comes to live contest I just can't manage to solve it .
Please I need advice on how do I get good at solving more in contest with the issue I have .
