00:00Hi everyone, today we are going to talk about a few things that you need to keep in mind

00:20when you are preparing for your computer science board exam.

00:23Sure, one revision will be done using the NCM.

00:29Now comes when you have the paper in your hand, make sure you read it very carefully.

00:35Read and understand each and every question carefully and check what exactly is to be

00:40done.

00:41Like here, if it is written by a statement, that means only one statement to be given.

00:47A very common mistake happens, children just read that they have to give the statement

00:52but they don't understand it's a statement means only one statement to be given.

00:56Then this question, where you are given a code snippet, you have to make the corrections

01:03and you have to mark the corrections, underline the corrections.

01:07So make sure when you are writing the code, the correct code, you mark each and every

01:13correction very carefully and very neatly.

01:16It should be visible that you have done something.

01:20As per the CVSE guidelines, we are not supposed to be using any other color pen other than

01:24the blue.

01:26So for underlining, use a pencil and mark it very correctly, including the indentation

01:34that you have written.

01:35The topics that you have, you're going to be getting at least three questions from file

01:41handling, one code to be written, one program question, coding question from each file,

01:48text file, CSV file, finally.

01:52They generally come with these ratings.

01:55Yeah, there are always chances that binary might come up four or CSV might come up three,

02:03but most of the time, this is how it is.

02:07Then you have stack, you get one question from stack in which you will be having push

02:12and pop functions to be given.

02:14Other than that, depending on the weightage of the question, you are asked to write the

02:19functions.

02:20It can be a display function or a search function, or you have to check whether the stack is

02:25empty or what is at the top.

02:27Any kind of function can be there.

02:29So one stack question, most probably a four marker will be there.

02:35Then there is one question for connectivity.

02:39It can be that you are given a question, you have to write the code, or it can be you are

02:47given a code where a few statements are missing.

02:50So you have to fill in.

02:52So there is one question.

02:54It can be either of three marks or four marks, or at times even two marks, there can be one.

03:00Now the next is MySQL, the unit which is, I would say, the most boring.

03:06Here you get 30 questions, 30 questions, one mark, two marks, three marks, like one marker

03:12may even get questions like you're given a relation, you have to check the cardinality

03:16or the degree of that relation.

03:18Even two or three marks, questions like DBL statements or DML statements or short note

03:26or difference between various commands, these kind of questions can be there.

03:31Other than the theory questions, you have to write queries.

03:35There are questions where statements are given, depending on that, you have to write the query.

03:39While writing the query, make sure to check the name of the table and use the correct

03:46field names given in the table.

03:49Don't cut short them.

03:51Write whatever is written there.

03:53Then there are questions where queries are given, you have to give the output.

03:58Here, you have to make sure when you are giving the output, you must make a table.

04:04When you are writing the output, make sure to draw the borders of the table with a pencil.

04:11That's very important.

04:13Then from your computer network chapter, you get different kind of questions.

04:19It can be an MCU, it can be a one marker or two marker, but there's one five mark case-based question.

04:30One very important thing, this chapter has many short forms, short forms of various protocols,

04:37various devices or technologies.

04:40So make sure you learn the full forms as well when you are learning or when you are reading

04:44or understanding about those terms.

04:49Make sure to learn their full forms as well.

04:53And last but not the least, I understand computer science is a practical subject.

04:59I've been doing all your code on the table, but right now it's clear to me.

05:05So make sure when you are practicing your code, write it down.

05:10Don't practice it on the system, practice by writing on the table.

05:16That's it for now.

05:17I wish all of you all the best.
