Thank you very much for great advice. I greatly appreciate them. They make me feel relieved . I will be more honest to him. @fuzzylogician It's just when he asked stuffs like "How are classes / semester?", I answered like "they are good/ok". I don't think I am lying or hiding information from him, but I should be more careful not to cross the line. @sjoh197 You got it right. I do feel intimidated by him. The Prof. is very distinguished and "special". He can exert a strong pressure (probably like the Force in Star Wars ) on you when you are having a conversation with him.

Hi friends, I have been working in a lab during my undergrad. I have good relationships and publications with the grad students. The professor seems to like me because I work very hard and have a passion for the project (He gets to know me mostly from the grads though.) My problem is that I got 3 grades of C in my transcript. One of them was due to a super difficult class & prof (~5 B were given for that class by thr prof.) The professor knew about this grade when I applied to the lab (he was unhappy, but somehow he agreed to let me work in his lab.) Unfortunately, I performed poorly in the next semester and got the other two C. The professor does not know about them. Worse, everytime he asked me about my studying I said it was good and tried to be a smart student. However, my overall gpa is good (~3.6ish) for a highly ranked engineering program. I am worried that he would not write me a rec letter for my phd applications. I dont want to tell him now because I love working in his lab. Do you think he will give me a LOR? What do you think I should do? Thank you very much. I greatly appreciate your comments
