Tips To crack CCEE


Some tips for CCEE

Java / DBT / WPT -

•These modules are scoring modules & takes only 30 min to solve the paper. 

•If you are good in concepts can easily score 30+ marks.

 

•Java topics/concepts to prepare –

o OOPS concepts – 4 pillars, class & objects, constructors, static, non-static, final, access specifiers, interface etc.,

o Collections – why we use, when we use, what are the different types & how they differ from each other, thread safe or not, insertion order maintain or not, null value accepts or not, repeated value stores or not, only value or key-value pair, sizes & how much increase etc.

o Multi-Threading – code snippets on start, wait, notify & concepts also.

o Packages – class belongs to which package? Like StringBuilder, StringBuffer, Thread etc.

o String – code snippets

o JVM, JDK, JRE

o Stack & heap memory – reference stored in stack & object stores in heap

o Garbage collector

o Exception handling – code snippets & concepts

 

•DBT topics/concepts to prepare –

o DBMS intro, RDBMS

o DDL, DCL, DML, DTL commands, difference between drop, delete and truncate etc.

o Normalization forms 1, 2, 3, BCNF, 4, 5 – concepts like what is required to have for normalization form.

o All keys, aggregate functions, WHERE, LIKE, DISTINCT, UNION, NULL

o Stored procedure - concepts

o Cursors - concepts

o Triggers – concepts

o Error Handling and Exceptions – concepts

o NoSQL, why? & examples of NoSQL

o MongoDB – concepts & commands

 

• WPT topics/concepts to prepare –

o HTML all tags, some concepts like how to import css,js file.

o CSS – apply color, border etc.

o Javascript – code snippets on promises & one-line questions like how to define array in Js.

o nodeJs – concepts & code snippets on its modules

o express – code snippet on routing

o ReactJs – concepts like props, components, hooks etc and code snippet

 

OS / DSA

• These modules test takes whole 60 min to solve because of problems/numerical.

• Problems looks difficult but easy to solve because they are only for 1 mark.

 

• OS topics/concepts to prepare –

o COP – variables, operators, loops, control statements, functions & oops

o Linux commands

o Process scheduling algorithms numerical– FCFS, Shortest Job First, Priority, RR

o fork()

o Parent, child, zombie, orphan process

o Signals

o Memory management - First Fit, Best Fit, worst Fit, paging & segmentation.

o Deadlock – how it occur, mutex, semaphore, Deadlock prevention and avoidance

o Page replacement algorithms

o IPC – concepts

 

• DSA topics/concepts to prepare –

o Time complexities – searching & sorting.

o Basic Data Structures – Array, stack, queues

o Linked lists – singly, doubly, circular, insertion deletion - codes and time complexities

o Trees – problems - traversal and concepts – AVL, ACBT

o Graph – problems - traversal, prim’s, Kruskal, Adjacency Matrix & list

o Hash functions and hash tables – problem- linear or quadratic probing

o Sorting – which one is better in which condition?

 

ASDM

o If you have read and understood all concepts of SDM then can score good marks

o Git & GitHub commands – 5-6 questions

o Docker/Docker swarm/Kubernetes/Jenkins/Jira– why we use, there applications, concepts and basic commands.

o SDM concepts – agile, scrum, v-model, SDLC etc….

o Virtualization, cloud, aws, EC2, S3

o Microservices and DevOps

o Testing – black, white & Gray

o Selenium

 

Advanced java / .Net

• These modules require good luck.😁

 

•Advanced java topics/concepts to prepare –

o Servlet

o Session Management

o Design Pattern: MVC Pattern

o Life cycle of a JSP page

o JDBC

o Bean

o Hibernate

o Annotations

o Hibernate

o Spring framework

o IOC, dependency injection

o JPA annotations

 

•.Net topics/concepts to prepare –

o .net framework concepts like cts, clr, jit etc.

o C# - basics, oops, params, ref, out, delegates, struct, enum, LINQ, etc.

o ASP.net

o ADO.net
