Physical Chemistry- Some Basic concepts in Chemistry,States of Matter, Atomic Structure, Chemical Bonding and Molecular Structure,Chemical Thermodynamics, Equilibrium, Surface Chemistry,Chemical Kinetics and Redox Reactions and Electrochemistry.  

According to me your main focus at this moment should be your board exams and if you are in CBSE board then it will be a bonus as a huge part is common for both the exams. In board exams, revision is the key to scoring marks. It's also important for JEE Main that you remember all the formulae so that you don’t miss on the easy questions.

NCERT books are known for being the best while preparing for JEE Main and 12th board exams.

Along with studying the syllabus, practical studying is also a good option while preparing for JEE Main and 12th board exams. Sample papers and questions banks will help you know how the exam pattern will be.

Good luck! 

Many of the students prepare the exam without coaching, It all depends on your capability, If you are clear with the basic Concepts studied in B.tech then It will easy to understand the new concepts.

Here are some preparation tips for GATE preparation you can prefer.

Understand syllabus properly:

You must be aware about the GATE syllabus, released by the organizing 

IIT. You must go through the section-wise and topic-wise syllabus of 

your chosen branch in order to know what all you have to study and what to avoid.

Solve previous year papers: Solving previous years papers is of utmost importance if you want to excel in the exam.

Weightage of Topics: it is advisable and important to study the complete GATE Syllabus, however, you can do a small exercise to gauge which sections, topics are much more important in terms of weightage given in GATE.

Resources other than books: It is good to look up topper and expert tips in this regard as they do mention the books or material they have referred to. Many GATE toppers run their own Facebook pages or blogs where they dispense advice and tips to wannabe GATE aspirants.

Remember the following points:

 Divide the Topics broadly into Strong, Weak and to be read properly.

Next schedule your preparation such that you revise the easy ones along with the tough ones and the “never read before” ones. This will ensure you have a clear view of what is to be studied and how you are going to do it.

While many advise to check the weightage and study accordingly, it is really not the correct way to go.

Check the weightage by all means and understand the important topics but don’t neglect to study.

Make Short Notes while you study as this is will be helpful during revision.

Write down Formulae that you find difficult to remember so that they are handy for revision.

Keep the solved problems separately indexed so that you can refresh and revise later when required.

Analyse your preparation at every step.

No it is not compulsory to join any coaching classes for JEE exams. You can study on your own and prepare well.
Do not get demotivated. All you need is the dedication and honesty towards studies.
But if you think you do need help then you can attend some coaching classes crash courses.
Try to cover all the important topics and also make a note of topics that are given more weightage to and start to study these topics properly. Do not waste time. Study NCERT thoroughly .
Try to clear all your concepts about any topic you have covered.
Give importance to all the three subject physics, chemistry and maths as in JEE all of them have equal weightage.
Practice Practice and Practice!!!
Note down all the formulas and important concepts so that they become handy for revision. Talk to your teachers they will be more than happy to help always and of course internet is always there. You can also post your questions on careers360 so that we can help you. 
Take online mock tests. 
Improve your calculation speed.
Keep on solving sample papers and previous year papers regularly and time all your papers so as to analyse your speed and result.
Focus on tricks to solve your questions rather than wasting time on lengthy calculations.
Don’t get upset and do not loose confidence if your score is less in earlier attempts as it would automatically gain a pace with time. keep practicing
Also I won’t advice you for late night studies, Sleep Early so as to keep your mind active and fresh.
And the most important advice don’t let anyone or anything break your flow.
Study with dedication and honesty, you will never fail.

Hope this helps.
Thanks
